Kate O’Brien, Conan’s Sister, Makes Acting Debut In ‘The Fighter’

Many people have never heard of Kate O’Brien. At least that was the case up until last night, when Amy Adams made an appearance on Conan, and the two chatted about the host’s sister.
 

Kate O’Brien is Conan’s sister who is breaking into the acting scene. She makes her acting debut in the upcoming film “The Fighter,” which stars Mark Wahlberg, Christian Bale and Amy Adams. O’Brien plays Phyllis ‘Beaver’ Ecklund – the sister of Wahlberg’s character Mickey.
