With his grizzled moustache and chiselled features, Charles Bronson is the embodiment of a slightly archaic, brooding and almost reactionary virility. But who is he really? Often hired to play marginalised Native American or Mexican characters before he was typecast as the image of a lone killer, Bronson was a major figure in the popular cinema of the 1960s and 70s and his stony-faced, physical acting and career are worthy of a second look.
