An Amazon Prime free-to-me streamer, a colorized version of the 1932 movie. Very watchable, in a goofy way. They don't make 'em like this any more.
Joel McCrea plays a mighty big game hunter, Bob, who's returning home on a private yacht. The yacht's captain notices some odd placement of warning buoys, but the yacht's owner says, never mind that, power on through. And before you can say "I bet I know what happens next", the yacht runs into a nasty reef. Except for Bob, those who weren't blown up or drowned get eaten by sharks. (This is pretty explicit and scary.)
But Bob washes up on a convenient island, and his jungle wanderings bring him to an imposing fortress. It's the domain of exiled Russian Count Zaroff; he's very welcoming and hospitable. There are two other "guests", also shipwreck survivors, Eve (Fay Wray!) and her brother Martin (Robert Armstrong). At first Bob's just happy to be alive, but even he begins to notice there's something a bit off about the whole situation.
OK, I'll tell you: Zaroff is a psycho, and his whole lifestyle revolves around getting people to his island, then hunting them down for sport. But has he met his match in Bob?
The IMDB trivia page is pretty cool. Most notable: the island sets were used in the concurrent filming of King Kong, as was also, of course, Fay Wray.
