This movie had one of the best whistle in any movie I've seen.
The story is about psychosis, Hayley Mills plays Susan Harper, a young student who tries to help a rich, emotionally ill and sinister young man, Martin Durnley (Hywel Bennett). Martin is a schizophrenic who assumes the personality of a six-year-old boy when he is in his "nice" phase. Susan talks a store manager out of pressing charges against Martin after he steals a toy duck. Martin wants to take the toy to his mongoloid brother, who is in an institution. Martin's stepfather, Henry (Frank Finlay), enraged by his shoplifting, evicts Martin despite the pleas of his mother, Enid (Phyllis Calvert). Martin, again acting like a young child, is taken in by Susan's mother, Joan Harper (Billie Whitelaw), who runs a boarding house.
Do you that scene from Kill Bill where Elle Driver is walking down the corridor in the hospital and she starts whistling that awesome but menacing whistle, yeah do you know that first came from? yep this movie and that's the only reason I checked it out because of that, after seeing the movie I can say that this a pretty damn good horror movie and the most overlooked horror movie I've seen.
Hayley Mills as the main psychopath of the movie dose a brilliant and a menacing little creep that got under my skin, because Martin or George (The main character psychopath) acts like a man child as he acts like he hasn't grown up yet and everyone treats him like a child, but really his a pure psycho and that pretty much explains why he acts like a little kid just to act innocent and fool everyone. Now when I think about it it's kind of nerving that this guy acts like this and that just add to unsettling nature of are main killer and Hayley Mills did a outstanding performance playing this character.
The director of the movie Roy Boulting which this is my first movie that he directed that I've seen and Roy Boulting did great behind the camera filming the unsettling and the uncomfortable scene where Martin was in and the director really set the scene very well. He made this movie look like if Alfred Hitchcock directed it.
The rest of the cast did fine in they roles, Martin was a interesting psychopath and the ending to the movie was even more uncomfortable and I think that's what made this movie stand out and doesn't hold anything back and just goes for it.
Now for problems with the movie: Some of the writing in the movie was a bit well how can I say it, oh yeah wooden and corny. Some of the other characters in the movie I didn't really care about to be honest, I only cared about Martin the killer because well he's so messed up that makes him more interesting.
Overall Twisted Nerve is a good overlooked horror movie that at times felt like a Alfred Hitchcock film at times.
