In 1998, he appeared in the music video for the song "Sunday" by the rock band Sonic Youth. In 2000, Culkin returned to acting with a role in the play Madame Melville, which was staged in London's West End. In the spring of 2003, he made a guest appearance on the NBC sitcom Will & Grace. His role as Karen Walker's deceptively immature divorce lawyer won him favorable reviews. Culkin headed back into motion pictures in 2003 with Party Monster, in which he played a role very different from those he was known for; that of party promoter Michael Alig, a drug user and murderer. He quickly followed that with a supporting part in Saved!, as a cynical wheelchair-using, non-Christian student in a conservative Christian high school. Though Saved! only had modest success at the box office, Culkin received positive reviews for his role in the film and its implications for a career as an adult actor. Culkin began doing voice-over work, with appearances in Seth Green's Robot Chicken. In 2006, he published an experimental, semi-autobiographical novel titled Junior, which talked about Culkin's stardom and his shaky relationship with his father.
