VIDEO: Conan O'Brien's Sister Makes Acting Debut in 'The Fighter'
Conan isn't the only O'Brien in the business.
The talk show host's sister, Kate, has a small part in the Golden Globe-nominated The Fighter. (She is sitting second from right on the couch around the eight-minute mark in the video below.)
"She's great," star Amy Adams told O'Brien on his TBS show Wednesday night. "That's why you gotta go see the movie."
Kate, who lives in Boston, where the movie was filmed, plays Phyllis "Beaver" Ecklund, one of the rambunctious sisters of Mark Wahlberg and Christian Bale's characters, which are based on the real-life family of boxer Mickey Ward.
