The Return of Doctor X

Had this film not cast Humphrey Bogart as the title mad scientist, this film would probably regarded as just another 1930's big studio "B" thriller. Bogart tries hard , but he is Bogart, and its just to hard to take seeing him playing an executed mad scientist brought back from the dead who is now a scientific vampire. Supposedly, Boris Karloff was slated to play the title role, but was not available.

I have to admit I was very impressed with the films art direction (credited to Esdras Hartley.) The laboratory of Dr. Flegg consists of a maze of glass tubes dripping a dark fluid in beakers, and has the look of a giant circulatory system, reflecting the films emphasis on blood.

Hollywood legend has it that Bogart was having trouble with WB brass at the time with the type roles they were giving him. The WB brass wanted to punish him by casting him in this and KING OF THE UNDERWORLD in order show Bogie who was boss.
