A new clip from "Ant-Man's" gag reel shows how stars like Paul Rudd, Michael Peña and Michael Douglas really found their groove on set. Rudd in particular hams it up, earning laughter from the crew as well as his fellow cast members.

Directed by Peyton Reed and starring Rudd, Douglas and Evangeline Lilly, "Ant-Man" is available digitally now, and arrives on Blu-ray and DVD on Dec. 8.
