Ant-Man has been in development at Marvel since 2006, two years before Marvel Studios released Iron Man. Marvel was unhappy with the direction director Edgar Wright and co-writer Joe Cornish had taken the story, which caused a dissolution of the partnership. The film was delayed by a couple of months as Marvel sought out Peyton Reed to take over production, with Adam McKay coming into do a script polish two months ago.

While most of the original cast remains, including Paul Rudd and Michael Douglas in the leads, actor Patrick Wilson stepped away from his role due to scheduling issues caused by the delay.

Ant-Man follows con-man Scott Lang (Paul Rudd), who must harness his inner superhero to help his mentor Dr. Hank Pym protect his spectacular Ant-Man suit from a new generation of towering threats. Armed with the astonishing ability to shrink in scale but increase in strength, and against seemingly insurmountable obstacles, Pym and Lang must plan and pull off a heist that will save the world.
