Ant-Man is the name of several fictional characters appearing in books published by Marvel Comics. Ant-Man was originally the superhero persona of Hank Pym, a brilliant scientist who invented a substance that allowed him to change his size. Hank Pym was created by Stan Lee, Larry Lieber, and Jack Kirby and first appeared in Tales to Astonish #27 (Jan. 1962); his first appearance as Ant-Man was in Tales to Astonish #35 (Sept. 1962).
After Pym retired his Ant-Man identity, successors Scott Lang and Eric O'Grady have used Pym's technology to take on the role of Ant-Man.
Ant-Man is an upcoming American superhero film based on the Marvel Comics characters of the same name: Scott Lang and Hank Pym. Produced by Marvel Studios and distributed by Walt Disney Studios Motion Pictures, it is intended to be the twelfth installment of the Marvel Cinematic Universe (MCU). The film was directed by Peyton Reed, with a screenplay written by Adam McKay and Paul Rudd, and stars Rudd, Evangeline Lilly, Corey Stoll, Bobby Cannavale, Michael Peña, Judy Greer, Tip "T.I" Harris, David Dastmalchian, Wood Harris, Jordi Mollà, and Michael Douglas. In Ant-Man, Lang must help defend Dr. Pym's Ant-Man technology and plot a heist with worldwide ramifications.
Development of Ant-Man began in April 2006, with the hiring of Edgar Wright to direct and co-write with Joe Cornish. By April 2011, Wright and Cornish had completed three drafts of the script and Wright shot test footage for the film in July 2012. Pre-production began in October 2013 after being put on hold so that Wright could complete The World's End. Casting began in December 2013, with the acquisition of Rudd to play Lang. In May 2014, Wright left the project citing creative differences, though still received a story credit with Cornish. The following month, Reed was brought in as Wright's replacement and McKay was hired to contribute to the script. Principal photography took place between August and December 2014 in San Francisco and Metro Atlanta.
