Hitchcock attended a strict Jesuit school from age eleven to almost fourteen. He later recalled that the school placed particular emphasis on fear, realism, and reason as key traits of religion. Whatever Hitchcock may have said about the role of religion in his life and work, that education remained a lifelong influence. As McGilligan writes: “The fear, the realism mixed with fancy, the reasoning power and discipline of ordered thinking—these were the cornerstones of his art” (McGilligan 24). Not only that, but they helped shape his view of the world.
The mind behind Alfred Hitchcock’s body of work is preoccupied, even obsessed, with questions of goodness and evil, innocence and guilt. Screenwriter Arthur Laurents, who worked with Hitchcock on the 1948 film Rope, observed that it was “obvious to anyone worked with him that he had a strong sense of sin” (quoted by David Sterritt in the essay “The Destruction that Wasteth at Noonday: Hitchcock’s Atheology”). Rope itself is an excellent example of this, with its tale of two young men who are inspired to commit murder by their former housemaster’s Nietzschean philosophies about superior beings and their right to act as they please.
