Trivia:
In the Book "Its only a movie", Hitchcock said like this about Torn Curtain's ending - "THERE WAS AN ENDING written for Torn Curtain", Hitchcock said "which wasn't used , but I rather liked it. No one agreed with me except my colleague at home (Alma). Everyone told me that you couldn't have a letdown ending after all that. "Newman would have thrown the formula away. After what he has gone through, after everything we have endured with him, he just tosses it. It speaks to the futility of all, and its in keeping with the kind of naivete of the character, who is no professional spy and who will certainly retire from that nefarious business." (more)
