- attributed to Humphrey Bogart

Although this is one of the best known catch-phrases associated with the tough-guy screen image of Humphrey Bogart, he never made the remark at all.
The association arose from Bogart’s 1942 film “Casablanca.”
He played a nightclub owner who was haunted by the song ‘As Time Goes By,’ because it reminded him of his love for the film’s heroine, played by Ingrid Bergman.
In fact, it was Miss Bergman who said ‘Play it, Sam’ to the club’s pianist, over-coming his boss’s injunction against the song.
Bogart heard the tune and realised that his lost love had returned.
His wrath for Sam was forgotten.
