The Ape Man is a 1943 horror film starring Bela Lugosi.
Watch it online, compliments of the Internet Archive, though the sound's not very clear:
The sound may be clearer through GoogleVideo, but it includes commercials:
Moria gives it one star and calls it "one of the numerous Z-budget mad scientist cheapies that Bela Lugosi made a career out of during the 1940s." 1000 Misspent Hours gives this a negative review, literally, giving it negative 3 stars and closes by saying, "no fan of Bela Lugosi at his most debased should miss it."
