Join Arachna of the Spider People and her friend Deadly as they host Beware Theater - The Devil Bat.  Kindly doctor Carruthers seeks vengeance on his employers by creating giant killer bats in this 1940 Poverty Row Studios cheepie. Bad acting - bad directing - cheezy special effects - a stupid plot - and a really fake looking bat. What's not to like when Bela Lugosi is in the starring role as a mad scientist - yet again.
