Mexican filmmaker Alfredo B. Crevenna directed this sci-fi thriller loosely based on the classic H.G. Wells novel. Augusto Benedico stars as Luis, a scientist who gives his new invisibility formula to his jailed brother, Carlos (Arturo de Cordova). Carlos escapes and is reunited with his beloved Beatriz (Ana Luisa Peluffo), but the invisibility potion turns him into an insane megalomaniac who plans to rule the world. The invisible madman murders Luis and begins committing acts of sabotage until Beatriz tricks him into a standoff with police. This overwrought version of the tale makes an interesting contrast with James Whale's 1933 version of the same story, which seems positively subdued by comparison.
