9. Paul Rudd
To get in shape for Ant Man, Paul Rudd dropped alcohol and carbs. He called it the Chris Pratt regimen, a nod the Pratt’s transformation for Guardians of the Galaxy. Prior to Ant Man, audiences knew Rudd for everyman comedy roles like the one he played in “This is 40.” The day Rudd landed the role, he hit the gym. Prior to Ant Man, he’d never worked out for an extended period of time. Although Rudd had been out of shape for some movies, he wasn’t necessarily overweight. The changes he made were more about where he wore his weight. He turned into an athlete for Ant Man.
