Diesel's first film role was a brief uncredited appearance in Awakenings (1990). He then wrote, directed, produced, and starred in the short film Multi-Facial (1994), a short semi-autobiographical film which follows a struggling actor stuck in the audition process. The film was selected for screening at the 1995 Cannes Festival. He made his first feature-length film, Strays (1997), an urban drama in which he played a gang leader whose love for a woman inspires him to try to change his ways. Written, directed, and produced by Diesel, the film was selected for competition at the 1997 Sundance Festival, leading to an MTV deal to turn it into a series. He was then cast in Steven Spielberg's 1998 Oscar-winning film Saving Private Ryan on the poignancy of his performance in Multi-Facial. In 1999, he provided the voice of the title character in the animated film The Iron Giant.
