John Powell (born 18 September 1963) is an English composer, best known for his scores to motion pictures. He has been based in Los Angeles since 1997 and has composed the scores to over fifty feature films. He is particularly known for his scores for animated films, including Antz, Chicken Run, Shrek (all three co-composed with Harry Gregson-Williams), Robots, Happy Feet (and its sequel), three Ice Age sequels, Rio, and the How to Train Your Dragon film series, for which he was nominated for an Academy Award for the first film. He has also scored many live-action films, of which his collaborations with directors Doug Liman and Paul Greengrass are perhaps the best known.
