In 2007, she played Leah in Juno. Around this time, she and her Juno co-star Elliot Page were slated to star as the respective title characters of Jack & Diane as two young women who fall in love which unlocked lycanthropy in one character but both dropped out before production, and the cast was replaced numerous times over. She plays Stephanie, a marijuana-smoking "popular girl" from New York City, in Sundance Audience Award-winning mid-1990s period piece film The Wackness, which was released in the U.S. on July 3, 2008, and stars opposite Josh Peck.
