ANDREW: [in background] You went out with Liam Neeson! Are you kidding me?
William “Liam” Neeson (born 1952), actor from Northern Ireland. He began his career in the Belfast theatre scene, and his first film role was in Excalibur (1981). He rose to prominence playing the title role in Schindler’s List (1993), starred in dramas such as Nell (1994) and provided the narration for Everest (1998). In November 2002, his most recent films were Stars Wars: Attack of the Clones and K-19: The Widowmaker, although Gangs of New York was just about to come out. He has received numerous honours, including an OBE in 2000.
Liam Neeson was married to actress Natasha Richardson in 1994, a marriage which lasted until her death in 2009. Presumably, Andrew’s dance partner went out with Liam Neeson prior to his marriage (or prior to him meeting Richardson, which took place in 1993).
