Paul Rudd's Son Couldn't Care Less About His Dad Playing 'Ant-Man'

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.
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."
Unlike physique, swagger doesn't come with training -- a lesson Rudd's son Jack taught him the hard way.
"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."
In Ant-Man, Paul Rudd plays Scott Lang, a thief who must aid his mentor Dr. Hank Pym (Michael Douglas) in safeguarding the mystery of the Ant-Man technology, which gives its user the power to decrease in size while increasing his strength.
Ant-Man opens July 17.
