Laura has a couple of nice twists.
Gene Tierney’s character, Laura, is murdered, shot in the face by a shotgun. Everyone suspects her shady fiancee, Vincent Price, as he seems to be hiding something. Then Laura turns up alive, and everyone’s shocked (twist 1). The dead woman turns out to be a girl that Vincent Price was seeing on the side. Clifton Webb, Laura’s obsessed former boyfriend, shot her by mistake, trying to murder Laura (twist 2). Dana Anderson plays a child’s puzzle and a tough detective throughout.

Yeah, I thought of Laura too, but the “twist” comes in about the middle of the movie. The second “twist” is just your standard mystery resolution: in a good mystery–which Laura is–the killer should always be something of a surprise. So I don’t think it counts as an honest to god “twist,” which as I see it should suddenly re-frame the entire movie from a new perspective, like the examples in the OP.

Another Hitchcock film: Suspicion.
Then there’s The Bad Seed, which has not so much a twist ending as a wussout ending. In the novel – and the Broadway play, I’m fairly certain – at the end, Rhoda’s mother, Christine Penmark – the only one who knows Rhoda is a murderous psychopath – dies, leaving Rhoda free to work her mischief on the world. Deliciously chilling! In the movie, Christine surives her suicide attempt while Rhoda is struck down by a deus ex machina – while her mother lies in the hospital, the psycho hellbitch is fishing at the end of a pier, at night during a thunderstorm, for another kid’s swimming medal she thinks should have been hers (so she killed him), and a bolt of lightning hits a tree, knocking down a bough which kills her. Meh. No doubt a cowardly concession to the moral sensibilities of the period which produced Dr. Wertham and the Comics Code Authority. "Good shall be portrayed as triumphing over evil in every instance . . .
The Bad Seed, BTW, is about to be remade.
Wonder how they’re gonna end it this time?

The ending of* The Bad Seed* was imposed by the Hays Office, the Hollywood censorship authority. Hollywood buckled to Catholic activists in 1934 and agreed to end all movies with evildoers receiving punishment, even if it made no sense to the rest of the plot. So any adapted story without such a denouement had one tacked on by the censor. (This lasted until 1967.) So, more nitpicking here, I don’t think that really counts as what the OP is looking for.
The Italian zombie flick Nightmare City ends with it all being a dream…but then things actually start happening that mirror the dream!
Can’t remember the name of it, or most of the plot, but there was a B&W movie where at the end they revealed that the two characters (I think they were supposed to be brother and sister) were in fact the same person… voice over man warned you not to tell your friends cos they’d kill you :eek: 
The Maze was an old B&W movie about a crowd of people staying in a old castle the twist being that the heir to the place (or whatever) is
I was coming to to mention what Rodgers01 beat me to. That’s pretty early, and it surprised me.
Witness for the Prosecution, 1957 - although staged as a play for decades prior.
Not really one big twist, but overall very twisty: Sleuth, 1972.

Anyways, the first golden oldie with a twist ending that I can think of is The Cabinet of Dr. Caligari.

Rats. I was just about to mention that one.
