Twisted Nerve (1968) - Opening Credits

Twisted Nerve (1968) - Roy Boulting
Martin Durnley is a young man with an infantilizing mother, resentful stepfather and an institutionalized brother with Down’s syndrome. To cope, he retreats into an alternate child personality he calls Georgie. After being caught during a theft attempt at a department store, he befriends a female customer who is sympathetic to him, but his friendship soon turns into obsession.
The whistling theme from the score was resurrected in Kill Bill: Vol. 1 (2003). As well as this, it was also used in various episodes of American Horror Story (2011) season one.
