In 'The Change-Up' Ryan plays a handsome playboy who switches bodies with a family man (Jason Bateman). Before the switch, they both envy each other's lives until they actually have to live in the other man's shoes.
Ryan kidded about why he decided to do the film, saying, "My whole life I've wanted to get inside Jason Bateman ... and here I was."
Leslie Mann plays Jason's wife in the movie and she described what it's like working with the two funny men on the same project.
"When you get them together they try to outwit each other ... because they're both so funny," Leslie said. "And half the time I don't know what they're talking about."
