[1] Born in Staten Island, New York, Sexton made his film debut in Todd Solondz's Welcome to the Dollhouse playing the troubled bully Brandon McCarthy, for which he was nominated for an Independent Spirit Award.
[2] He was the lead in Hurricane Streets[3][4] and Desert Blue and also appeared in Boys Don't Cry, Black Hawk Down, and Just Like the Son, as well as the cult films Empire Records and Pecker.
Sexton owns and operates a New York City-based independent record label Big Bit of Beauty.
In a 2002 radio interview, Sexton said that the version of the film Black Hawk Down, in which he briefly appeared, which made it onto theater screens was significantly different from the one recounted in the original script.
According to him, many scenes asking hard questions of the U.S. troops with regard to the violent realities of war, the true purpose of their mission in Somalia, etc., were cut out.
