movie trivia: here's looking at you kid...

"Here's looking at you, kid" was improvised by Humphrey Bogart in the Parisian scenes and worked so well that it was used later on again in the film. He originally used the same line in Midnight (1934). It is also rumored that during breaks, Ingrid Bergmanwould play poker with other cast members. Since she was still learning English, Bogart would occasionally watch the game, and he added "Here's looking at you" to her poker repertoire.
