Jennifer Aniston Opens Up

Don't tell Garcia, but Owen has had dogs around him since childhood. "I felt like in a way I have been preparing my whole life for the role [in Marley & Me] because we grew up with family dogs," he says. From Nutmeg the dalmatian to Duke the golden retriever, dogs have been a big part of the Wilson family since Owen was just a boy.

Owen's dog-loving parents even make a cameo in Marley & Me. While Owen says his mom was a little nervous, his dad felt right at home. "My dad kind of was a little bit cocky—like right after his first take he said to me, 'Is it too early to say a star is born?'" Owen jokes.
