 "THERE WAS AN ENDING written for Torn Curtain",  Hitchcock said "which wasnt used , but I rather liked it. No one  agreed with me except my colleague at home (Alma). Everyone told me  that you couldnt 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."
