Its sometimes hard to remember that before he was a bad director of bloated, pompous films, Richard Attenborough was an fine actor in sharp, pointed ones.
Here he completely immerses himself completely in drab evil as Christie, the mild-mannered mass murderer who let a halfwit (John Hurt, starting his run of geeky victim roles) hang for his crimes, and then continued his killing spree before setting his sights on a young coupe in the flat upstairs.
A precursor to movies like Henry: Portrait Of A Serial Killer in its mood and interestingly directed by Richard Fleischer. Rillington Place, incidentally, had its name changed.
