Martin is a troubled young man. With a mother who insists on treating him like a child, a stepfather who can’t wait to see the back of him, and a brother shut away in an institution, is it any wonder he retreats into an alternate personality…that of six year old Georgie? It is Georgie who befriends Susan Harper, but friendship soon turns into obsession. When Susan begins to distance herself, something inside Georgie snaps and he embarks on a killing spree, with Susan as the next target. —IMDb
The twin brother of John Boulting, producer/director Roy Boulting spent the bulk of his film career in partnership with his sibling. Both men attended Toronto’s McGill University, both entered the British film industry in the early 1930s, and both teamed to form Charter Films in 1937. In most of their subsequent film projects including Thunder Rock (1942), Desert Victory (1943), Single-Handed (1953), Brothers in Law (1957) and Twisted Nerve (1968), John produced and Roy directed. Their positions were reversed in films like Brighton Rock (1947) and Heavens Above! (1963). In 1963, the Boultings joined the board of the directors of the flagging British Lion Film Corporation, and have been credited with bringing that sleeping giant back to life. While both brothers evinced a preoccupation with droll wit and satire, they were adept at virtually any film genre. Evidently, it was Roy Boulting who enjoyed the most active social life; among his six wives was actress Hayley Mills. —britmovie… read more
The antagonist is like a living embodiment of Hitchcock's "bomb under the table" theory on suspense. The audience is well aware of Martin's motivations from the start, his obsession with Susan and his potentially volatile relationship with authority, but the supporting characters are oblivious. From this, Boulting is able to create some great moments of tension and anxiety through the positioning of Martin in everyday situations where his egotistical morality may be challenged.
