Robert Aldrich's blazing adaptation of Mickey Spillane's gut-wrenching nuclear age potboiler turns a well-worn genre on its head and retains its power to shock almost 50 years after it was made. Ralph Meeker yells his way through this movie as the quintessential Mike Hammer: loud, boorish, sexist, bullying and gleefully violent. Watch out for the back-to-front titles and apocalyptic climax. Truly the greatest private-eye movie ever made.
