Dracula, Frankenstein, the Mummy, the Wolf Man, and the Invisible Man were reinterpreted and ripped off countless times, often by Universal itself. And with the Invisible Man, the studio chose to keep the franchise running with an ahead-of-its-time gender twist. It centers on an eccentric scientist (Claude Rains), whose bandage-concealed face arouses the suspicion of his small town home. As remains the case for any horror movie, once you have a hit, the studio wants sequels. Later remakes and re-imaginings of the Invisible Man narrative would focus more on the sinister implications behind its science.
