From the old and extremely rare Japanese laserdisc, here's a scene that was severely edited for home video release for decades that shows Dr Frankenstein (played by the great Peter Cushing) using his mouth (because his hands had been burned in a previous film in the series) to help his assistant clamp an artery in his latest creature's newly transplanted hands.
I've got this on dvd years ago, plus when I saw it on TV as a kid this scene was shown ???
