Humphrey Bogart and Ingrid Bergman in Casablanca (1942)
Humphrey Bogart and Lauren Bacall in Dark Passage (1947).
Humphrey Bogart as detective Philip Marlowe in The Big Sleep (Howard Hawks, 1946)
one of my favorite movie lines of all time.
Six lines from Casablanca appeared in the AFI list: AFI’s 100 Years…100 Movie Quotes, which is the most of any film.
