Public Enemies (out Jul 30) is a terrific new film from Michael Mann. Set in the 1930s, it focuses not just on John Dillinger's famous bank robberies but also on the methods used by the police to hunt him and his cronies down. There are some great shoot-outs (with archaic rifles) and strong performances, particularly from Christian Bale and Marion Cotillard. Johnny Depp was not quite as good. Grade: A-.
