Ant-Man
A former systems engineer at VistaCorp and petty criminal, who acquires a suit that allows him to shrink in size but increase in strength. Regarding Rudd's casting, producer Kevin Feige said, "Look at that origin of the petty crook who comes into contact with a suit and does his best to make good, and then look at someone like Paul Rudd, who can do slightly unsavory things like break into people’s houses and still be charming and who you root for and whose redemption you will find satisfaction in." On the character, Peyton Reed said, "He's not used to being a hero. He's more like George Clooney's character Danny Ocean in Ocean's Eleven. He’s a guy trying to create a new life for himself and find redemption." To get in shape for the role, Rudd worked with trainers and cut alcohol, fried foods and carbohydrates out of his diet. Rudd stated that in preparation for his role, he "basically didn’t eat anything for about a year ... I took the Chris Pratt approach to training for an action movie. Eliminate anything fun for a year and then you can play a hero." Rudd signed a multi-film contract with Marvel, with Feige saying it was "three[ films]-plus-plus to appear in other things."

Trivia

 * The story of how Scott Lang got into Hank Pym's life and became the second Ant-Man from the comics is different here. There, it was Scott who got into the life of Hank Pym, by stealing his Ant-Man suit for her daughter's operation. While here, it actually seemed to be Hank Pym, as he was looking for new users of his creation, the Ant-Man suit that can help protect the Earth and his discoveries and creations.
