Marvel has found its Ant-Man!
Joseph Gordon-Levitt was also in talks for the role but just announced his involvement in another superhero flick— DC's "Sandman."
If you're not familiar with the character, Ant-Man is one of Pym's alter-ego superheroes with the ability to shift between human and microscopic size.
In the comics, he also goes by other aliases including Goliath — who can make himself ginormous.
Edgar Wright ("The World's End") will direct the film.
"Ant-Man" is set for release July 31, 2015.
The film will be the first release after Marvel's big "Avengers" sequel May, 2015.
