Joseph Losey's film has acquired something of a reputation since it's release way back when, though it's hard to see why. Stanley Baker playing the eponymous villain is convincing enough but the script and characterisations are weak. This is particularly evident in the prison scenes which comprise most of the film. The incarcerated are stock characters so beloved of British films of this period and they perform true to type (ie terribly). The exception is one of Beckett's favourite actors Patrick Magee, his sinister prison guard is a real stand-out. Aside from his performance the other outstanding feature is the photography from Robert Krasker which, ironically, suggests what a great film this could have been.
