Very funny in spots ("How did I ever graduate?" - "I slipped that guy 20 bucks!"), slow-going in others (despite the complete and welcome absence of any musical numbers), "Abbott and Costello Meet The Invisible Man" is probably not one of the duo's best films from a purely comedic standpoint, but it is nevertheless fascinating, if only for its amazing special effects. Clever, elaborate photographic, editing and other tricks are employed to achieve such effects as the invisible man removing his bandages from his head which is completely transparent while the rest of his body is not ("There is no reason to lose your head over this", observes Lou) - effects that in our digital age would probably be achieved by pressing some buttons in a computer. That's why you have to appreciate the effort and creativity that went into making such things happen. (**1/2)
