Supergirl Movies & TV Series
Supergirl Comic Books
Supergirl is a fictional character, a superhero featuring in comic books published by DC Comics. Supergirl was created to be a female counterpart to DC's popular hero Superman. She was created by writer Otto Binder and designed by artist Al Plastino in 1959. She first appeared in the Action Comics comic book series and later branched out into animation, film, television, and merchandising. In May 2011, Supergirl placed 94th on IGN's list of the Top 100 Comic Book Heroes of All Time.
Introduced in 1959, a number of different characters have assumed the Supergirl mantle over the decades, with the most popular and enduring version of the character being Kara Zor-El, Superman's cousin, who shares his super powers and vulnerability to Kryptonite. Supergirl plays a supporting role in various DC Comics publications, including Action Comics, Superman, and several comic book series unrelated to Superman. In 1969, Supergirl's adventures became the lead feature in Adventure Comics, and she later starred in an eponymous comic book series which debuted in 1972 and ran until 1974, followed by a second monthly comic book series titled The Daring New Adventures of Supergirl, which ran from 1982 to 1984.
Due to changing editorial policy at DC, Supergirl was initially killed off in the 1985 limited series Crisis on Infinite Earths. DC Comics subsequently rebooted the continuity of the DC Comics Universe, re-establishing Superman's character as the sole survivor of Krypton's destruction. Following the conclusion of Crisis on Infinite Earths, several different characters written as having no familial relationship to Superman have assumed the role of Supergirl, including Matrix, Linda Danvers, and Cir-El. Following the cancellation of the third Supergirl comic book series, starring the Linda Danvers version of the character, a modern version of Kara Zor-El was reintroduced into the DC Comics continuity in issue #8 of the Superman/Batman comic book series titled The Supergirl from Krypton (2004). The modern Kara Zor-El stars as Supergirl in an eponymous comic book series, in addition to playing a supporting role in various other DC Comics publications.
The first live action depiction of Supergirl was in the eponymous 1984 British superhero film directed by Jeannot Szwarc, starring Helen Slater as Supergirl, Faye Dunaway, and Peter O'Toole. It is based on the DC Comics character of the same name and is a spin-off to Alexander and Ilya Salkind's Superman film series.
The film is a spinoff from the Superman film series starring Christopher Reeve, to which it is connected by Marc McClure's character Jimmy Olsen (he was the only returning actor). Its plot concerns Supergirl, Superman's cousin, leaving her isolated Kryptonian community of Argo City for Earth in an effort to retrieve the unique "Omegahedron", which has fallen into the hands of the evil witch Selena (Faye Dunaway). The film was poorly received and did poorly at the box office.
Justice League Unlimited (2004-2006)
Justice League Unlimited (JLU) is an American animated television series that was produced by Warner Bros. Animation and aired on Cartoon Network. Featuring a wide array of superheroes from the DC Comics universe, and specifically based on the Justice League superhero team, it is a direct sequel to the previous Justice League animated series. JLU debuted on July 31, 2004 on Toonami and ended with the episode aired May 13, 2006. It was also the final series set in the long-running DC animated universe, which started with Batman: The Animated Series in 1992.
Supergirl (2015 CBS TV Series)
Supergirl is an American superhero fiction action-adventure drama television series developed by Ali Adler, Greg Berlanti and Andrew Kreisberg (the latter two having previously created Arrow and The Flash) that airs on CBS. It is based on the DC Comics character Supergirl (Kara Zor-El), created by Otto Binder and Al Plastino, and stars Melissa Benoist in the title role. Supergirl is a costumed superheroine who is the biological cousin to Superman and one of the last surviving Kryptonians. The series was officially picked up on May 6, 2015, after receiving a series commitment in September 2014, and premiered on October 26, 2015. Supergirl received a full season order of 20 episodes on November 30, 2015.
SUPERGIRL is an action-adventure drama based on the DC Comics character Kara Zor-El, Superman’s (Kal-El) cousin who, after 12 years of keeping her powers a secret on Earth, decides to finally embrace her superhuman abilities and be the hero she was always meant to be. Twelve-year-old Kara escaped the doomed planet Krypton with her parents’ help at the same time as the infant Kal-El. Protected and raised on Earth by her foster family, the Danvers, Kara grew up in the shadow of her foster sister, Alex, and learned to conceal the phenomenal powers she shares with her famous cousin in order to keep her identity a secret. Years later at 24, Kara lives in National City assisting media mogul and fierce taskmaster Cat Grant. She works alongside her friend and IT technician Winn Schott and famous photographer James Olsen, who Grant just hired away from the Daily Planet to serve as her new art director. However, Kara’s days of keeping her talents a secret are over when Hank Henshaw, head of a super-secret agency where her sister also works, enlists her to help them protect the citizens of National City from sinister threats. Though Kara will need to find a way to manage her newfound empowerment with her very human relationships, her heart soars as she takes to the skies as Supergirl to fight crime.
24-year old Kara Zor-El, who is taken in by the Danvers family when she was 12 after being sent away from Krypton, must learn to embrace her powers after previously hiding them. The Danvers teach her to be careful with her powers, until she has to reveal them during an unexpected disaster, setting her on her journey of heroism.
On September 4, 2014, it was reported that Berlanti would executive produce a re-imagining of the origin of Supergirl, to be written by The New Normal and Chuck alum Ali Adler. Flash co-creator Johns is also involved with development. On September 19, 2014, it was reported that CBS had made a series commitment to Supergirl. It was also announced that Berlanti would co-write the first episode.
In November 2014, Berlanti expressed interest in Supergirl existing in the same universe as his other series Arrow and The Flash, and in January 2015, The CW president Mark Pedowitz revealed that he was also open to a crossover between the series and networks (due to Berlanti executive producing all three and The CW co-owned by CBS). However, Tassler stated that month that, "those two shows are on a different network. So I think we'll keep Supergirl to ourselves for awhile."
Melissa Benoist as Kara Zor-El / Kara Danvers: A 24-year old Kryptonian living in National City who must embrace her powers after previously hiding them. She is Cat Grant's assistant at CatCo. Benoist expressed her excitement over portraying the character, and being able to "[tell] a story about a human being really realizing their potential and their strength". Claire Holt and Gemma Atkinson were under consideration for the role. Malina Weissman will portray a young Kara.
Mehcad Brooks as James "Jimmy" Olsen: A former Daily Planet photographer living and working in National City for Cat Grant as her new art director and love interest for Kara.
Calista Flockhart as Cat Grant: The founder of media conglomerate CatCo.
David Harewood as Hank Henshaw: A former CIA agent who is the head of the Department of Extra-Normal Operations (DEO), who goes on high alert when Supergirl reveals herself, worried that her otherworldly abilities pose a threat to humankind.
Chyler Leigh as Alexandra "Alex" Danvers: Kara's foster sister and a doctor who will try to learn as much as she can about Kara's Kryptonian culture. She works for Henshaw at the DEO.
Catherine Jane "Cat" Grant
Catherine Jane "Cat" Grant is a fictional character appearing in American comic books published by DC Comics, commonly in association with Superman. Cat first appeared in Adventures of Superman #424 (January 1987) as a gossip columnist for the Daily Planet. Introduced as a potential love interest for Clark Kent, her character added a new dimension to the Clark/Lois Lane/Superman dynamic.
- Cat Grant appears in the series Supergirl, portrayed by Calista Flockhart. She is depicted as the founder of media conglomerate CatCo and is the mother of Carter Grant.
- In Lois & Clark: The New Adventures of Superman, Cat Grant was featured in her early role as the Daily Planet gossip columnist with an interest in Clark Kent. She was played by Tracy Scoggins. Cat was portrayed as a shameless man-chaser, who tried to seduce Clark Kent very often - to the point that she once tried to convince him that they were involved when he was suffering from amnesia- and usually dressed in provocative attire. Scoggins was a regular cast member during season one, but the character was dropped for the remainder of the series, without explanation.
- The character of Cat Grant was considered by the producers of Superman: The Animated Series, but was dropped in favor of the character Angela Chen (voiced by Lauren Tom) that would add more diversity to the Superman cast of characters. Chen's role mirrored Grant's from the comics, with the exception that she was a TV news-magazine host and that she was Half Black-Half Asian, and that she viewed Superman in a proper manner as opposed to a potential love interest.
- Two incarnations of the character appeared in Smallville. In the season nine episode "Crossfire", Clark Kent applies for a hosting job for a TV morning show; he tries to impress the producers with a piece on online dating, and goes on a blind date with Cat Grant (Emilie Ullerup). Cat's character is the opposite of her usual portrayal: she is studying for two advanced degrees and served in the Peace Corps. At the end of the episode, she is hired instead of Clark to host the morning show. On July 25, 2010, it was revealed at Comic Con that actress Keri Lynn Pratt would play a new version of the character in the final season. This version of Cat works at the Daily Planet and is partnered with Clark during Lois Lane's absence. The character mentions the previous Cat Grant, and explains the identical name as a coincidence. It is later revealed that her real name is Mary Louise Shroger, and that she changed her name to protect her son. The character was recurring throughout the final season. She takes a stand against vigilantes on the grounds that they steal the spotlight from "real heroes". Her life is threatened several times by Deadshot and later Isis, but she is saved each time by Clark. Her opposition to vigilantes prompts her to expose Lois, Tess Mercer and Emil Hamilton to the authorities.
- Cat Grant appears in the Young Justice animated TV series in a recurring role voiced by Masasa Moyo. First appearing in the episode "Targets", she is seen reporting on a peace conference that is being officiated by Lex Luthor. In the episode "Terrors", Cat is seen broadcasting news reports from New Orleans and Chicago where the Terror Twins are doing a three-state rampage. In subsequent episodes, she continues to appear (usually briefly) reporting the news on WGBS-TV while the main characters watch.
Supergirl Episode 1: "Pilot" October 26, 2015
In January 2015, Melissa Benoist was cast in the role of Supergirl. CBS launched a trailer for the series in May 2015. The series premiered on October 26 2015. On May 22 2015, the pilot episode was leaked online and made available through many torrent sites in high-definition (1080p), with fans wondering if the leak was due to theft or a marketing stunt by CBS.
A young girl named Kara Zor-El is sent to Earth by her mother Alura to protect her cousin, Kal-El, as their planet, Krypton, destructs. The planet's explosion forces her ship off course and into the Phantom Zone, where she stays for 24 years before landing on Earth. Kal-El, now an adult and going by the name Superman, puts Kara in the care of the Danvers. Twelve years later, Kara is forced to reveal herself to the world when her adoptive sister's plane is sabotaged and she must save everyone. Her sister, Alex, is revealed to be working at the Department of Extra-Normal Operations, under the leadership of Hank Henshaw, investigating alien activity.
She learns that there are hundreds of aliens on the planet in hiding, most whom came from a prison that crashed on Earth when she did, and that her mother was the one responsible for imprisoning the intergalactic criminals. Her actions attract the attention of Vartox (Owain Yeoman) and, with guidance from Alex, she is able to defeat him. New art director James Olsen reveals he was sent to look after her and presents Kara with a gift from Superman, a new cape for her costume. Vartox's superior is revealed to be Astra In-Ze, Alura's identical twin sister, who wants to conquer Earth.

The DEO prepares an ambush for the Hellgrammite, but it escapes, kidnapping Alex and taking her to Astra. Astra uses Alex as a trap for Kara. As Kara and Astra fight, Hank injures Astra with a Kryptonite knife and Alex kills the Hellgrammite. Learning that Kara has become more powerful than she had imagined and that humanity has a means of weakening Kryptonians, Astra muses that her "plans" may need to be temporarily postponed.

Cat Grant is out of town accepting an award and Kara, James, and Winn struggle to take care of CatCo, Cat's son Carter, and a bomber targeting Maxwell Lord's company. The DEO, claiming to be the FBI, goes to Lord and attempts to convince him to postpone the bullet train's opening, but to no avail. Kara is stuck between James and Lucy's relationship, each arguing that the other is responsible for their breakup. On the opening night of Lord's new bullet train, Supergirl and the DEO must deal with two bomb threats simultaneously, one at the airport and one on the train. James and the DEO go to the airport, where Hank Henshaw secretly uses his hidden strength to deactivate the bomb, claiming it was a dud. Supergirl goes to the train, on which Carter and the bomber are both riding. As Supergirl confronts the bomber, he claims that he is doing it for his invalid daughter. The bomber requests Supergirl save the people on the train after he starts the timer, which she does.

Kara is distraught over both this defeat and the fact that Cat will fire her unless she is convinced that Kara is not Supergirl. Kara goes to the DEO and talks with Astra who tells her that Alura believed her (correct) claim that Krypton was doomed, but sentenced her for her illegal methods while promising to work for her cause. Alex and Supergirl make the trade over Lane's objections and Astra orders Non to withdraw despite his numerical advantage.

On May 12, 2016, Warner Bros. Television announced that the series had been renewed for a second season and that it would move from CBS to The CW. It is scheduled to debut in October 2016.
Flash & Supergirl 2016 Musical Cross-Over
Ever since The Flash debuted set within the same universe of The CW’s prior hit Arrow, crossovers have been a #DCTV staple on The CW. This fall will feature The CW’s first ever four-episode crossover, spanning not only Arrow and Flash, but Supergirl and DC’s Legends of Tomorrow as well. However, today the Executive Producers announced that next season will also feature a two-part musical crossover taking place later in the season between Supergirl and The Flash.
If you’re scratching your head over this, you shouldn’t be. Both Melissa Benoist and Grant Gustin were regulars on Fox’s Glee and are more than capable of carrying a tune, along with fellow stars Jesse L. Martin (Joe West), John Barrowman (Malcolm Merlyn), Victor Garber (Martin Stein) and Jeremy Jordan (Winn Schott). As for how the rest of the cast is at crooning, we’ll find out when the musical crossover takes place in the second half of the season.
Supergirl Season 2 (CW 2016-2017)
Along with the news about the musical crossover, there were some exciting character and casting announcements made today about the newest #DCTV show to join the CW family.
Fans of Young Justice and Teen Titans may be excited to learn that Miss Martian will be showing up on Supergirl next season, played by Grimm’s Sharon Leal. Considering we’ve only met one other White Martian on Supergirl so far and he was downright terrifying, it’ll be interesting to see what sort of relationship Leal’s character will have with Martian Manhunter.
Also appearing this season on Supergirl will be Mon-El, played by actor Chris Wood (Containment). Mon-El will first show up in Supergirl’s season premiere and traditionally has powers very similar to Supergirl and Superman’s, despite hailing from a different planet. Wood’s been cast as a series regular, so we know Mon-El will be a significant presence when Supergirl returns in the fall. Whether the show will make any nods to the Legion of Super-Heroes, however, remains to be seen.
Finally, the producers also announced that Kevin Smith will be directing an episode of Supergirl in Season 2. Smith, of course, also directed a well-regarded episode of The Flash last season (and will be back to direct another episode in Flash Season 3).
