Her first major film role was as the protagonist of Lawn Dogs (1997), a drama co-starring Sam Rockwell. She appeared in major pictures such as the romantic comedy Notting Hill (1999) and M.

KaBlam! is an American animated sketch comedy anthology television series that ran on Nickelodeon from October 11, 1996 to January 22, 2000, with repeats until November 2, 2001. The series was created by Robert Mittenthal, Will McRobb, and Chris Viscardi. The show was developed as a fully animated showcase for alternative forms of animation that were more common in indie films and commercials. Each episode thus features a collection of short films in different innovative styles of animation, bridged by the characters Henry and June, who introduce the short animations and have zany hijinks of their own in between.
