In her first feature film role, Nicholson starred opposite Michael Caine and James Spader in the Peter Yates film Curtain Call. Later she won what proved to be both her breakthrough and favorite role as a headstrong young feminist in Peter Chan's The Love Letter. She has worked with other international directors in films such Alain Berliner's Passion of Mind, and Nick Hurran's Little Black Book. Nicholson's domestic drama credits include William Vincent (Jay Anania), Staten Island (James DeMonaco), Brief Interviews with Hideous Men (John Krasinski), Tully (Hilary Birmingham), Kinsey (Bill Condon), and August: Osage County (John Wells), for which the ensemble cast was nominated for several awards.
