England, 1872. The night before he is to be hanged for a murder he did not commit, young Dr. Gordon Ramsey is visited in his cell by his old mentor, eminent surgeon Sir Joel Cadmund. Cadmund offers to see that Ramsey gets a proper burial and gives him a sleeping powder to get him through the night, which Ramsey takes, unaware it is really an East Indian drug, "nind andhera" ("the black sleep"), which induces a deathlike state of anesthesia. Pronounced dead in his cell, he is turned over to Cadmund, who promptly revives him and takes him to his home in a remote abbey. Cadmund explains he believes Ramsey is innocent and needs his talents to help him in an project, which he is reluctant to immediately discuss further. In fact, Cadmund's wife lies in a coma from a deep-seated brain tumor, and he is attempting to find a safe surgical route to its site by experimenting on the brains of others, whom Ramsey comes to learn are alive during the process, anesthetized by the "black sleep", and ...

Great fun and not a great film--but what a roll call of horror greats! Lugosi's last real role.
2 September 2013 | by (United States) – See all my reviews

The Black Sleep (1956)

This is one of those campy horror movies, two decades after the great originators, that fans will really love and newbies or outsiders will have trouble getting.

I'm mostly a fan, but even as the titles rolled and I couldn't believe the great cast, I was aware that this was 1956, that Bela Lugosi and Lon Chaney Jr. were well past their prime. And the lead, Basil Rathbone, was playing an evil doctor (a shade like Dr. Frankenstein, pushing moral boundaries with his surgery), was more known as Sherlock Holmes. Still, along with John Carradine, what a cast!

And this is really Lugosi's last uncompromised appearance in any movie, even though he plays a mute and we don't get to hear him. ("Plan 9" comes after this, but Lugosi's role there is famously limited.) He's terrific! And Chaney's appearance is also mute, a brief each time, and not such a big deal. (Once there is nice, corny subjective p.o.v. camera as he attacks his prey.)

The plot? The title? Well, it's all a bit obvious what's happening, though the opening twenty minutes is more a straight drama that actually suggests a really good movie is ahead. A man is on death row, and Rathbone visits him and gives him the Black Sleep potion, which puts him into a fake death and he is carted away and revived. That doesn't give too much away. For the rest of the movie the potion is really just used as anesthesia at the crazy doctor's castle and is no big deal.

There is the pretty girl in a coma, a misunderstood nursing assistant who is daughter of the Chaney character, another nurse who is oddly cold and efficient (and not a Nazi--this is all 1872), and then there is the main character, the man from death row, who happens to be a crack surgeon that the evil doctor needs for his research.

For the middle half of the movie you see minor tensions and some brain surgery that is meant to seem cutting edge and unscrupulous. Then, in a huge surprise, almost as if the director woke up, a bunch of old patients appear out of nowhere (maybe they escaped their cells). And it's a bit of absolute mayhem, with Carradine playing an angry Moses type, and it's pretty crazy.

Look, I said too much perhaps but you should know this isn't a great movie. But it's great camp. It's silly, it's filled with icons from the old days, and it's not so badly made at all, edited well and filmed better than you would think for this nadir of Hollywood productions. This is around the time of the new Castle low budget films, and early Corman stuff, but this one is clearly from the old school of 1930s Hollywood. See it on those terms and like it!
