Conan's sister Kate O'Brien made her acting debut in "The Fighter," playing Phyllis "Beaver" Eklund. "I work at a school and someone said, 'They're casting [The Fighter], you should go down, you look Irish Catholic,'" Kate O'Brien told People. "I'm one of six, so it wasn't that hard for me to look like I might have more siblings."
