Casablanca (d. Michael Curtiz, 1942, USA), film assignment help

For this assignment, I want you to pick one character from Casablanca (d. Michael Curtiz, 1942, USA, 102 min.) and write a 150-200 word post in which you discuss what the film conveys about him or her when we first meet that character.  You can include things information we got before we actually meet the character (through things characters said, the impressions given by their house or office, or because we heard him or her off screen first (e.g. Sam singing)).  Acting style, how other characters react to them, and what props are associated with them all play into this
