Trejo was an ex-con working as a youth counselor when he arrived on set of Runaway Train to help a young crew member who was battling a substance problem. The director asked Trejo is he would like to be an extra in a prison scene and, in true Danny Trejo fashion, he said yes. Trejo has gone on to be in nearly 150 movies and is known for saying yes to any role he is asked to play.
