This action flop has aged so well to the point when you leave out Charles Bronson and Jill Ireland and most of the cast, the film moves into the realms of a minor (but most certainly unintentional) masterpiece. The stars undoubtedly had a pleasant paid holiday in Switzerland while making the film. Charles Bronson preferred Europe, so this ridiculous change of scenery was probably thrown in as it suited producer, director and stars.
Paul Koslo (the actor perpetually with the worst hair in Hollywood) is as always a lackey and fallguy who gets blown away. But this film really comes into its own with such a towering performance from Rod Steiger that one has to wonder why he wasn't nominated for an Oscar. 100% brilliant comedy send up - his speech impediment is a masterstroke, masterly executed. Steiger can be watched and rewatched endlessly, he's such a scream, while the end of the film one of the best blasts you'll ever see.
