Bela Lugosi will always be remembered as one of the greatest horror stars of all time for 'Dracula'. Less than ten years later he was forced to star in third rate material like 'The Devil Bat'. He had supporting roles in a couple of good movies like 'The Wolf Man' (with Lon Chaney and Claude Rains) and 'The Body Snatcher' (with Karloff) after this, but for the most part his career was in severe decline, culminating in the awful (but awfully entertaining) movies he made with Ed Wood, Jr. ('Glen Or Glenda', 'Bride Of The Monster' and very briefly, 'Plan 9 From Outer Space') 'The Devil Bat' is b-grade all the way, with a lousy script, uninspired direction, a ridiculous looking "devil bat", and a forgettable supporting cast, led by 'Reefer Madness' Dave O'Brien. The only reason to watch this is Lugosi. Sometimes he seems to be actually trying, at others he hams it up. Either way he's great to watch. He plays a scientist who works for a hugely successful perfume company. In his laboratory he experiments on a bat with electricity which makes it grow very large, and that, combined with his new aftershave which contains a Tibetan scent which enrages the bat(!), becomes his method or vengeance on his employers. You think I'm making this up, don't you? Look, this is a silly movie, but if you're a Lugosi fan you'll have fun.
