A schooner disappears at sea without a trace. Years later, evidence of possible survivors prompts the mother of the schooner's mate Jose to hire a tuna boat to investigate. They discover the lad living happily on a South Seas island, and, when he refuses to leave with them, they abduct him. However, Jose gets revenge by leading the ship into the lair of a mysterious giant manta ray. Written by Jeremy Lunt <durlinlunt@acadia.net>

Did You Know?


Not only was most of this film made of travelogue stock footage, but the acting was from dubbed old stock footage as well. Louise, the love interest, had the classic hairdo from the early 1930s, yet the film wasn't released until 1946. See more »

My vote for one of the 10 worst films of the 1940s.
14 February 2012 | by MartinHaferSee all my reviews

To call "Devil Monster" a film isn't really fair, as it's simply a crappy old film from a decade before that's been chopped to pieces, had narration and new dialog added as well as LOTS of irrelevant and cheap looking stock footage. As such, it's just a cut and paste job with no original content and this really was terrible to foist this pile of bilge on the public. It's a completely cynical attempt to squeeze a dime off unsuspecting people.

The plot is quite scant. A guy disappears and some folks go looking for him in the South Seas years later. They find him and try to force him to return home--and the man exacts his revenge. In the interim, there is lots of footage and stilted dialog--and absolutely none of it is interesting or worth your time. A truly terrible film with not a single redeeming feature. Heck, it's not even unintentionally funny like many bad films--just duller than dishwater.
