NOTORIOUS (1946): Following the conviction of her German father for treason against the U.S., Alicia Huberman takes to drink and men. She is approached by a government agent (T.R.

Alfred Hitchcock claimed that the FBI had him under surveillance for three months because the film dealt with uranium. Alfred Hitchcock and Ben Hecht consulted Nobel Prize winner Dr. Robert Millikan on how to make an atomic bomb. He refused to answer, but confirmed that the principal ingredient, uranium, could fit in a wine bottle. Both Cary Grant and Ingrid Bergman found the famous kissing scene quite problematic, according to Alfred Hitchcock, because of the complicated blocking that needed to be remembered in the several long takes that it took to shoot it. Alfred Hitchcock: About an hour in, at the party in Alexander Sebastian’s mansion, Hitchcock gets a glass of champagne from the bartender and quickly turns to the left and walks off screen. After filming had ended, Cary Grant kept the famous UNICA key. A few years later he gave the key to his great friend and co-star Ingrid Bergman, saying that the key had given him luck and hoped it would do the same for her. Decades later at a tribute to their director Alfred Hitchcock, Bergman went off-script and presented the key to him, to his surprise and delight.
