lifesoboring Intriguing and pretty bizarre, somewhat grotesque. Young girl character is a heroine par excellence. Evil guy is totally evil. Acting superb. Interesting setting. Was trying to figure out where movie took place (first guessed Mexico, then Spain. Location: Italy).The story unfolds excellently. Had my full attention throughout. Clever. All acting first rate. Dialog couldn't be better. Conclusion--one of best I've ever seen.Looked up young girl actress on this site and found out she only made movies thru her teen years, then retired (became an aux-pair in, I think, New York, then got married and lived a life of domestic bliss). Villain was typecast in other films as coldblooded Nazi.Has gotten me wanting to see more Hammer films.

adriangr Minor but entertaining Hammer thriller, not quite reaching the heights of other entries in their "psychological thrillers" ouevre, but still effective.The film starts right off with it's main murderer on screen committing his evil deed, clearly establishing his (and the film's) gimmick of the snorkel used as an accessory to murder. So from the very beginning we know this is not going to be a whodunnit. What we have here instead here is a "who will find out" plot. Once the opening credits have finished, the main plot of the film starts with the daughter of the murder victim feeling almost positive that she knows who is responsible for the deed but at the same time, unable to prove it, as nobody has been able to work out how the act was committed, and therefore the killer has got away with it. The more agitated the daughter becomes, the more the killer starts to see her as a threat to his freedom, and so a cat and mouse game starts to build as both try to outwit each other.This sounds complicated, and it is, but the roles in the film are quite well defined. The killer is a creepy but charismatic older man, able to convince everyone that he is actually mourning his dead wife, and the "suspector" is a teenage girl who everyone thinks is just over imaginative. I could almost imagine William Castle making this film! The acting is very good, and it's all very British and proper. There are plot twists and the climax is clever and worth waiting for, although as a whole the film has dated somewhat. Quite hard to see now, seemingly only available on the Sony 6 film box set DVD "Icons of Suspense", which is worth a purchase due to it having 5 other hard to see Hammer thrillers. So "The Snorkel" gets a thumbs up from me.

dbdumonteil ...but in much more tragic circumstances than the teenage young detective .This is an entertaining thriller,quite suspenseful,even if its title is some kind of spoiler.Peter Van Eyck is ideally cast as the villain but the ending would have been better if the last scene in the police station had been deleted : the last scene in the house might indicate that Mandy is losing her mind ,which was an interesting idea.The ending leaves no mystery,which is unworthy of Hammer .Watch it anyway !Peter Van Eyck is really scary with his snorkel while the young Many Miller,though not as brilliant as Pamela Franklin ,is quite good.

whpratt1 The beginning of this film is very strange with a man, Paul Decker, (Peter Van Eyck) crawling around in a dark room and turning off various connections and inserting hoses and then you see him wearing a snorkel. As the film moves on you begin to realize just what is going on and discover that Paul Decker is up to no good and has caused many deaths. There is a daughter who becomes suspicious of her father Paul Decker and she is constantly watching him and even goes to the police, but no one believes her. Jean Edwards, (Betta St. John) tries to help Paul's daughter because she also has a love relationship with Paul, and the daughter and father definitely do not get along. This film will hold your interest and entertain you right to the very end, which is really funny. Enjoy
