Amanda Bynes

After lending her voice to the long-running cartoon Rugrats, Bynes made the big switch from the PG world of Nickelodeon to the PG-13 world of the WB with a part on the short-lived series The Nightmare Room, narrated by author R.L. Stine. The next year she made her feature film debut in the comedy Big Fat Liar as the best friend of fellow young superstar Frankie Muniz. In 2002, she launched the WB sitcom What I Like About You, playing a comedic younger sister who moves into the trendy Upper West Side apartment of her straight-laced older sister (Jennie Garth from Beverly Hills 90210). Widely released one day after her 17th birthday, the romantic comedy What a Girl Wants marked her first major starring role and showcased her Sandra Bullock-style pratfalls as lead Daphne, a girl who goes to England in search of her father (Colin Firth) and finds romance. The undistinguished Just One of the Guys retread She's the Man followed in 2006, a year before she landed a plum supporting role in the big-budget musical remake of Hairspray. ~ Andrea LeVasseur, All Movie Guide
