Canadian actor Glenn Ford, who was made a Hollywood star with his typical roles of straightforward but troubled heroes in many hits of the 1940s, 50s and 60s, has died after a long illness. His cult movies include Gilda, classic Fritz Lang film noir The Big Heat, Blackboard Jungle, comedy with Marlon Brando Teahouse of the August Moon and tense thriller Experiment in Terror. Latterly he moved into television from the seventies onwards, but was chosen to play the adoptive father of Superman in the 1978 film of the same name.
