Return of the Ape Man is a 1944 American film distributed by Monogram Pictures.

[1][2] It was directed by Philip Rosen with top-billed star Bela Lugosi[3] and supporting actors John Carradine, George Zucco (see note in the Production section), Frank Moran, Judith Gibson and Michael Ames.

[5] George Zucco is co-credited on screen and in the publicity, along with Moran,[5] as having played the Ape Man.

At the onset of the laboratory scene where Prof. Dexter (Lugosi) and Gilmore (Carradine) are preparing to melt the caveman free from the block of ice, Zucco is shown in the Ape Man makeup - albeit briefly.

Zucco's prominent nose, as well as his injured and withered left arm/hand (from a WWI injury) are clearly visible facing the camera.
