Robinson's role is evocative of Duke Mantee in "The Petrified Forest" (1936), a Bogart leading man breakthrough the studio had originally earmarked for Robinson. The enormous success of "Casablanca" redefined Bogart's career. For the first time, Bogart could be cast successfully as both a tough, strong man and vulnerable love interest.

Humphrey Bogart Warner Bros. wanted to cast the then much better known Edward G. Robinson for the film adaptation; however Leslie Howard, who played the protagonist in both the play and the film, insisted on Bogart being given the part.

After they married, she also played his love interest in "The Big Sleep" (1946),
