Don't listen to the negative reviews

To all those who have watched it: I hope you enjoyed it as much as I do.

It's funny, it's tense, it features two great performances from two actors and the director expertly creates a web of odd tension where you actually don't know what is happening for the majority of the run time.

Watching it is like watching the spectacle of a class clown at their best: you laugh at their jokes, instigate their defiance, and "ooooh" when they get in trouble.

"The Man They Could Not Hang" is certainly a very watchable film. On the surface, it appears to be another mad-scientist-defies-nature story, but it has deeper roots.Dr. Henryk Savaard (Boris Karloff) has designed an artificial heart and has tested it on various animals. A young man volunteers to be the first human recipient, so Savaard and his assistant terminate the man's life only to be interrupted mid-procedure, before they can restore the man's life.What follows is a courtroom drama, then an Agatha Christie-like murder in a box, with a twist. At each phase of the film, Dr. Savaard delivers a speech about science vs. ignorance, each with its own perspective. Each speech is well written and takes the story beyond the typical mad doctor genre.This film does not fall into the horror genre. Perhaps the mere presence of Karloff prompted that labelling. But Savaard may be the most rational character in the film. It is a sci-fi crime story. And it is well worth watching and very entertaining.

I really, really liked "The Man They Could Not Hang"! It's definitely one of the best – probably even THE best – of all the "mad scientist" movies released during the 1930s / 1940s and starring the almighty Boris Karloff in the role of megalomaniac doctor or professor (and these are quite numerous)! In fact, I loved this particular movie so much that it was one of those rare occasions where I regretted the fact that horror movies from this era are so short and to-the-point! I usually think it's a giant advantage that these films only last like 60-70 minutes, but in case of "The Man They Could Not Hung", I really wished that Karloff's mad-raving behavior would last another half an hour extra! There were most other contemporary titles of this kind are soft and overly talkative, this one is non-stop packed with action, suspense and deeply fascinating medical theories! Brilliant scientist Henryk Savaard is on the verge of writing medical history with his invention of a mechanical heart that can bring dead patients back to life after they have been operated. Savaard's student/assistant volunteers to test the device, but his girlfriend goes haywire and alerts the police. They break into the laboratory before Savaard has the opportunity to resurrect his guinea pig and – boom – the poor doctor gets accused of murder and sentenced to death by hanging! In court, Savaard transforms from a civilized scientist into an insane killer and vows to destroy everyone responsible for his death: judge, jury, crazy girlfriend and skeptical colleagues! A few weeks later, they all receive an invitation to come to a secluded old mansion; Agatha Christie style! Here, there are awaited by their very much alive host Savaard and subjected to a series of vile death traps… What I personally liked most about "The Man They Could Not Hang" – maybe even more than the delicious 'old dark house' climax – is the realism of Dr. Savaard's research. To put it in his own absorbing words: "To operate on a living body is like trying to repair a motor when it's still running… It would make more sense to switch off all bodily functions during an operation and then turn them back on when the operation was successful". That actually makes sense! Savaard isn't just another crazed professor aiming at immortality or creating new life, but a devoted doctor with a vision! I was definitely supporting him before and during his trial, and even when he was extracting his vengeance (although admittedly he goes a little over-the-top there…). This is, simply put, a massively entertaining black-and-white chiller with a splendid screenplay and an excellent Karloff performance. Director Nick Grindé does a more than adequate job as well. He would make two more mad scientist movies with Karloff, namely "Before I Hang" and "The Man with Nine Lives", but this one is my favorite.

The Man They Could Not Hang is a very solidly done film but falls short of greatness. The ending is tacky and felt somewhat like two endings in one. The first third does take its time to get going, it sets things up well but compared to what comes after it was a little dull, while the music is rather stock and you can tell that several composers were responsible. The Man They Could Not Hang looks very good however with fluid photography and creepy settings, while the script is witty and clever with a foreboding tone that really makes its impact, and the story may be standard but it is still very neatly told with the suspense levels appropriately sinister and the fun factor deliciously entertaining. The last third apart from the ending fares by far the best, that's fun and enough to make you bite the nails. The acting is good, Lorna Gray comes off best in the supporting cast, all competent but none make the same impression that Boris Karloff. Karloff is good reason to see any film and he is the best thing about The Man They Could Not Hang. He has an effortless eerie command and does it with his usual style and dignity. The artificial heart and organ transplant stuff is also very ahead of its time, and a further source of interest. Overall, standard with a hokey ending, stock music and a slow start but lots of fun and very effective in atmosphere and as ever Karloff is great. 7/10 Bethany Cox

Man They Could Not Hang, The (1939) ** 1/2 (out of 4) Boris Karloff plays a crazed scientist who is obsessed with bringing the dead back to life. He tries his new machine on a dead college student but before he can bring the kid back to life the police show up and he is eventually sentenced to death. The scientist swears vengeance on the jury, judge and prosecutor if he can live through the hanging. This was the first of four "mad scientist" films that Karloff made for Columbia and it's certainly the weakest. The film starts off pretty well but it slowly grows tiresome and ends with a very poor finale, which is a cheat, silly and just comes off bad. Karloff is actually pretty good in the first half of the film as we see him really playing crazy like he wasn't offered too many times. Quite often he was the nice mad scientist but here is actually gets to come off pretty crazy and messed up in the head. This might take sympathy away from him for later in the film but I liked his character early on. The second half of the film turns into your typical revenge thriller and doesn't add anything new or original to the mix. The supporting cast is also rather disappointing even though Lorna Gray comes off fairly well. None of these Columbia films with Karloff are overly special but the good news here is that this one runs just over an hour, which makes for some mild entertainment but if you want to see classic Karloff then you'll have to look elsewhere.
