Roddy Doyle is an Irish novelist, dramatist and screenwriter. He is the author of eleven novels for adults, eight books for children, seven plays and screenplays, and dozens of short stories. Several of his books have been made into films, beginning with The Commitments in 1991. Doyle's work is set primarily in Ireland, especially working-class Dublin, and is notable for its heavy use of dialogue written in slang and Irish English dialect. Doyle was awarded the Booker Prize in 1993 for his novel Paddy Clarke Ha Ha Ha.

The Commitments is a 1991 musical comedy-drama film based on the 1987 novel of the same name by Roddy Doyle. It was directed by Alan Parker from a screenplay written by Doyle, Dick Clement and Ian La Frenais. Set in the Northside of Dublin, the film tells the story of Jimmy Rabbitte, a young music fanatic who assembles a group of working-class youths to form a soul band named "The Commitments". The film is the first in a series known as The Barrytown Trilogy, followed by The Snapper (1993) and The Van (1996).
