Humphrey Bogart & Ingrid Bergman in Casablanca (1942, dir. Michael Curtiz)
“Bogart’s response to the success of Casablanca was more typically sardonic. He enjoyed telling his fourth wife, Lauren Bacall, how Charles Enfield, the studio’s head of publicity, had the amazing revelation that the actor had sex appeal.
Says Bacall, ‘Bogie would say, ‘Of course, I did nothing in Casablanca that I hadn’t done in twenty movies before that, and suddenly they discover I’m sexy. Any time that Ingrid Bergman looks at a man, he has sex appeal.’”
