 Producer Hal B. Wallis (qv) considered Hedy Lamarr (qv) for the  role of Ilsa, but she was then under contract to MGM (which wouldnt  release her) and she didnt want to work with an unfinished script  anyway. She later portrayed Ilsa in a 1944 radio show based on movie  scripts, "Lux Radio Theater". At the time both  Ingrid Bergman (I) (qv) and Humphrey Bogart (qv) were overseas  entertaining the troops. Rick was played on radio by  Alan Ladd (I) (qv).
