An early low-budget spin on Ten Little Indians, this cheap but entertaining PRC production features a wonderful cast of familiar B-movie faces, particularly George Zucco and Lionel Atwill. Zucco plays a man wrongfully imprisoned after being framed for his wife's murder by one of his colleagues. After his release, he joins forces with a mad inventor to carry out his long-awaited plans of revenge, inviting a group of his former associates to a remote island mansion -- which is enveloped in a thick perpetual fog and rigged with a plethora of lethal booby-traps -- in an effort to reveal and destroy the guilty party. Rather cheap-looking but boasting some remarkable special effects, this film is worth a look for its pairing of the wonderfully hammy Atwill and Zucco. ~ Cavett Binion, Rovi
