Paul Rudd got into superhero shape for his role in Ant-Man, but that wasn't the only thing the comedian had to pull off for the movie. The role also required superhero swagger, which his son doesn't think he has.
NEWS: Michael Peña Reveals Why Paul Rudd Makes a Great Ant-Man
Rudd filled us in on how he got those rock-hard abs for the role, saying, "It's not like Rocky out in the snow carrying a log or anything, but it's weights and cardio and all that kind of stuff."

"When I told my own son that I was going to be in a super hero movie, he asked me what it was and I said I was going to be playing Ant-Man, and he was not impressed," Rudd told ET. "What he actually said was, 'I can't wait to see how stupid that'll be.' Swear to God, that's what he said."
