Even though her father is renowned playwright David Mamet, the unconventionally pretty actress hasn't had a particularly easy time breaking into the acting business. She recalled casting appointments, when "the look on those people's faces was one of confusion: 'What WAS that?" Sometimes a director or a writer or a casting director would fight for me, but the producer or studio executive would be like, 'No! We can't sell her.' "
