Rainey Dawn Before I hang is a pretty nice sci-fi crime thriller. I agree with others it's sorta a Jekyll and Hyde type of movie - but not a rip off. (Mad) Scientists have been in movies for years and this is one in that category. Worth watching if you like these types of films.Dr. John Garth (Karloff) is a scientist working on an experiment to prolong the human life, did a mercy killing and was sentenced to death by hanging for it. While on death row, the prison doctor and the warden became fascinated with the idea of living longer so the warden allowed, with the help of the prison doctor, Dr. Garth to continue his experiments until the walked death row. While doing the experiment Dr. Garth accidentally ended up mixing the blood of a real killer with the serum and was injected with it - this is where things change for Dr. Garth and the film.Make it a double feature with Karloff's The Man They Could Not Hang (1939). Nice classic 9/10

preppy-3 Kindly Dr. John Garth (Boris Karloff) is found guilty of a mercy killing and sentenced to hang. While in prison he experiments in trying to find a serum that halts old age. He uses the blood of an executed murderer and tries it on himself. He is then pardoned and finds the serum works...but it turns him into a cold-blooded killer which he has no control over.This is pretty much a forgotten movie and it's easy to see why. It's pretty slow and dull with terrible dialogue and questionable science. Also it's (technically) not a horror movie--it plays more like a melodrama with horrific touches. Wonderful actress Evelyn Keyes is in here too but is given nothing to do. Karloff single-handedly saves this from total disaster. He's just great in his role--he makes the worst dialogue sound like Shakespeare! Also when the killing urge takes over you can actually see the changes in his face and mannerisms and there are also some nice atmospheric scenes at the end. There's a funny lapse in continuity--Keyes finds out by the morning paper about a murderer--but a scene outside the house shows it's night time! This is really only for Karloff fans. I give it a 4.

Tranio1 Boris Karloff, typecast in the horror genre, was one of our most underrated film actors. Here is a typical film of his middle career that showcases his versatile skills, equally strong as the benign, elderly scientist and his murderous, strangling younger self. This b-picture packs a lot of atmosphere and suspense into it's hour running time. Any shortcomings cannot be blamed on anyone but the screenwriter, Robert D. Andrews, who was just trying to keep things moving- not such a bad thing, actually. Nick Grinde does an excellent job making the most out of the script and witness Karloff's fireside confession for an example of the film's above average cinematography. It's also nice to see Karloff side by side with Edward Van Sloan again nine years after Frankenstein. If you need proof of Boris Karloff's talent and charisma aside from Frankenstein, check out Before I Hang, as well as The Black Room, The Body Snatcher, and Targets. I wish we had a star like him today...

MARIO GAUCI The third Boris Karloff "mad doctor" film is an interesting if surprisingly rather dull affair; the star is always worth watching, however, and his role here certainly offers him plenty to sink his teeth into: he starts the film as an old man about to be hanged for a mercy killing, is then rejuvenated through a serum he develops while in prison (the kindly warden having consented to Karloff continuing his experiments there until the time of his execution comes) and finally turns into a strangler (the unfortunate side-effect of the drug which contained the blood cells of a murderer)! Though the supporting cast features several familiar faces, they're all somewhat underused: Evelyn Keyes and Bruce Bennett are certainly among the higher-prolife actors to fill the 'romantic interest' roles in this type of film, but they're just about the most thankless I've ever seen (especially Bennett who has barely 5 minutes of screen time)! Edward van Sloan's presence was especially welcome (having memorably faced-off with Karloff twice before) but, again, his prison doctor here is nowhere near as juicy as his iconic roles in Dracula (1931), FRANKENSTEIN (1931), THE MUMMY (1932) and DRACULA'S DAUGHTER (1936)! Pedro de Cordoba, on the other hand, is quite poignant as Karloff's pianist friend whose career is fading due to his advancing age; of course, Boris is willing to help him out in this regard, but his new-found and uncontrollable murderous instincts prevail! A measure of amusement is also gleaned from noticing the recurring presence of such actors as Roger Pryor, Don Beddoe and Charles Trowbridge in roles which were pretty much reprises of ones they had played in the earlier Columbia Karloffs! On the debit side, the low budget especially shows here in the film's rather dismal sets - the other three of Karloff's serious horror efforts for Columbia made good use of the star's gadget-filled house (THE MAN THEY COULD NOT HANG [1939]), frozen underground lab (THE MAN WITH NINE LIVES [1940]) and Karloff's imposing cliff-top mansion (THE DEVIL COMMANDS [1941]); besides, the rather clinical experiments become repetitive and the film talky, which is further exacerbated by the regrettable fact that throughout there are few action/horror highlights per se.As far as the film's DVD presentation goes, I found it to be disappointingly lackluster: while the print itself is adequate, there are no scene selections for any of the films in this set (which also proves to be the case with Universal's Karloff collection and the "Inner Sanctum" Set!) nor, for that matter, proper menu screens - have the studios become stingy or what?!
