This was only briefly shown in cinemas as a charge of plagiarism was filed and it wasn't seen for fifty years, until it fell out of copyright. Whatever the validity of the legal challenge, this is a typical Val Lewton horror, rich with atmosphere: of shadows and fog, and sea shanties; of arcane traditions of the sea and dense emotional anxiety.
RKO asked Lewton- the producer- to get some use out of the studio's water tank and a ship already built for another production. The Ghost Ship examines the deepest fear of its main character; Russell Wade plays an inexperienced Third Officer on his maiden voyage on a cargo ship, concerned that he lacks practical knowledge.
The captain (Richard Dix) is a martinet obsessed with authority, but also he lacks moral will. He always fails to act, resulting in death or danger, but has built a weird, crazy philosophy justifying his negligence. The novice begins to suspect the captain's sanity, but is isolated because everyone else on the ship is blind to these misfortunes, and he doubts his own judgement.
The tale is narrated by sailor who is mute; his poetic commentary is extremely pessimistic. There are extraordinary action sequences; when the anchor is returned to its locker, a labourer (debuting Laurence Tierney) gets shut inside by the skipper and slowly crushed to death. There is that touch of the peculiar that is characteristic of the Lewton horrors. It's a shame this brief, hallucinatory film isn't better known.
