THE MAN WITH NINE LIVES offers more food for thought than most "Budget pictures," the filmmakers giving their audience(s) more Bang for their Buck. Karloff is at his best, here, convincingly DRIVEN. His argument(s) may or may not hold water, depending on how averse you are to using living Human beings as guinea pigs (better Human Beings than guinea pigs, I'D argue). Just as impressive as the writing and Karloff himself is the Cinematography: the darkened dungeon in which most of the movie takes place is so beautifully shot that I'd suggest that anyone interested in cinematography get their hands on this one and study it.
