Jeremy Sisto became interested in acting when he was six. He started out doing plays at The Goodman Theater and also acted and directed plays in high school. His big break came when he was cast as Roberto in the film "Grand Canyon" when he was 16. Jeremy is probably best known for his performance as Billy Chenowith on the HBO series Six Feet Under. Some of his other memorable movies include Clueless, Suicide Kings, Thirteen, and Jesus (as the title character). He plays Knapp in the NBC series Kidnapped. Many are at times intrigued by Knapp’s role as a dogged investigator or reckless renegade. He is a professional who works outside the law's strict rulebook to retrieve kidnapping victims and guide families through the process.
