Liu first appeared on the big screen as an ex-girlfriend in Jerry Maguire (1996) (she had previously filmed a scene in the indie Bang (1995), but it was shelved for two years). She then waded through a series of supporting parts in small films before landing her big break on "Ally McBeal" (1997). Liu initially auditioned for the role of Nelle Porter, which went to Portia de Rossi, but writer-producer David E. Kelley was so impressed with her spunk that he promised to write a part for her in an upcoming episode. The part turned out to be that of growling, ill-tempered lawyer Ling Woo, which Liu filled with such aplomb that she was signed on as a regular cast member. The "Ally" win gave Liu's film career a much-needed boost-in 1999, she was cast as a dominatrix in the Mel Gibson action flick Payback (1999), and as a hitchhiker in the ill-received boxing saga Play It to the Bone (1999). The next year brought even larger roles: first as the kidnapped Princess Pei Pei in Jackie Chan's western Shanghai Noon (2000), then as one-third of the comely crime-fighting trio in Charlie's Angels (2000). Charlie's Angels: Full Throttle (2003). Kill Bill: Vol. 1 (2003).
