Director Peyton Reed has praised screenwriters Edgar Wright and Joe Cornish for the plot of the forthcoming Marvel film “Ant-Man.” In a recent conversation with Uproxx, Reed said that before stepping in as director he read all the previous drafts by Wright and Cornish.

“It was clearly Edgar and Joe’s idea to make this a heist movie and to sort of loosely base it on Marvel Premiere's 'To Steal an Ant-Man' that introduced Scott Lang. It was also their idea to create this Hank Pym-Scott Lang, mentor-mentee relationship,” Reed said. He also said the writers' idea to show a “third act battle in the little girl’s bedroom” was a genius stroke.

Wright was first hired to direct “Ant-Man” but left the project due to creative differences. The script was rewritten by "Ant-Man" star Paul Rudd and writer-comedian Adam McKay.

"Ant-Man" follows the story of thief Scott Lang (Rudd) who must aid his mentor Hank Pym (Michael Douglas) in order to safeguard the Ant-Man technology. He plots a heist as Ant-Man to save the world from evil. Reportedly, the plot of the film differs from the comic book, where Lang steals the Ant-Man suit to save the life of his daughter Cassie. In the film, he will accidently stumble upon the Ant-Man suit and will learn how to use its powers under the supervision of Pym.

The film also stars Corey Stoll as the main antagonist Darren Cross/ Yellowjacket, a former protégé of Pym who takes over Pym's company and comes up with his own version of Ant-Man suit, called the Yellowjacket.

Other cast members include Evangeline Lilly, Bobby Cannavale, Michael Peña, Tip "T.I." Harris, Wood Harris, Judy Greer and David Dastmalchian. Kevin Feige has produced it and Christophe Beck has supplied the music. “Ant-Man” will open July 17.
