O Monstro de Duas Caras

Ostracized by the scientific community, Dr. Jekyll is doing some rather pointless sounding experiments while his wife is cheating on him with his gambler friend. Unhappy with their relationship, he turns his experiments on himself and becomes the suave Mr. Hyde.

Another take on the Jekyll and Hyde story, this one has some interesting ideas, but it never does much with them. Ultimately, the film is quite dull. Too much focus is placed on Jekyll's poor marriage and the affair his wife is having. It might not have been so bad if his wife were actually desirable, but she's an annoying shrew. Jekyll should just rid himself of her and consider his life all the better for it. Christopher Lee plays the friend with whom she's having the affair. He's playing against type here and is actually sort of the protagonist, but it's hard feeling sympathy for a philanderer. Paul Massie plays Jekyll and Hyde. He's actually not that great as either. His line delivery just sounds unnatural, especially when he's playing Jekyll.

There are some interesting twists towards the end, but it's too little, too late. This isn't one of the better films from Hammer.
