This is what Hitchcock’s Rich and Strange was released as in the U.S. His title is better, because it comes from The Tempest: “Full fathom five thy father lies, / Of his bones are coral made, / Those are pearls that were his eyes: / Nothing of him that doth fade, / But doth suffer a sea-change / Into something rich and strange”

Fred and Emily Hill (Henry Kendall and Joan Barry) are on a cruise but seem to be falling in love with other people. Despite that, Emily still wants to take care of Fred, at least until he gives all their money to his new love, stranding them in Singapore and nearly sinking them until they’re saved by some Chinese folks who eat a cat. Yes, really. A 1931 movie is like that sometimes. Hitchcock even said it was one of his favorite scenes.

You can watch this on Tubi.
