Twisted Nerve is a 1968 British psychological thriller film directed by Roy Boulting and starring Hywel Bennett, Hayley Mills, Billie Whitelaw and Frank Finlay. The film follows a disturbed young man, Martin, who pretends, under the name of Georgie, to be intellectually impaired in order to be near Susan—a girl with whom he has become infatuated. Martin kills those who get in his way. Plot Martin plays catch with his older brother Pete, who has severe learning difficulties and has been sent to live in a special boarding school in London, by their mother. Martin is the only remaining figure in Pete's family life; their father died years ago and their mother has a new life with her new husband, a wealthy banker. Martin expresses concern for his brother's well-being to the school's physician, who is comfortable with Pete's situation, though he makes it clear that Pete cannot be expected to live much longer. After the title sequence, Martin is shown in a toy store, gazing at Susan, who purchases a toy. As she leaves, Martin follows after having pocketed a toy duck. Two store detectives ask them to return to the manager's office. The detectives assert that Martin and Susan were working together to allow Martin to steal a toy. Susan assures them she has never met Martin. When questioned by the manager, Martin presents himself as mentally challenged, and calls himself "Georgie". Apparently now disbelieving in a link between them, the manager asks Susan for her address, and Martin appears to make a mental note when she offers it. Sympathetic to him, Susan pays for the toy. Implying that this was a misunderstanding, the manager lets them leave. Martin returns home and finds his parents arguing in the parlor, over his lack of interest in life. Despite the apparent course of events in the toy shop, they have come to hear of the duck. There is allusion to some perverse behaviour he has exhibited, though this is not elaborated upon. In his room, now behaving as "Georgie", he rocks in a rocking chair while smiling meekly in the mirror and caressing a stuffed animal. The camera pans down to reveal that the rocking motion of the chair is smashing a photo of his stepfather. The next day, Martin goes to Susan's house and waits for her to return. She arrives with a young Indian man named Shashee. He
