It's easy to forget that before the dark days of Golan-Globus, Charles Bronson was once one of the most promising actors of his generation. In movies like the Magnificent Seven and Once Upon a Time in the West and classic episodes of shows like the Twilight Zone and Have Gun Will Travel, Bronson gave a series of powerful but subtle performances.
Bronson first made the transition to leading man in the late Fifties in Man with a Camera. Check out this episode directed by William Castle and co-starring Angie Dickinson.
