 The difference in height between Humphrey Bogart (qv) and  Ingrid Bergman (I) (qv) changes throughout the film. This is  because Bergman was actually a few inches taller than Bogart, though  to create the illusion that it was vice versa, Michael Curtiz (qv)  had Bogart stand on boxes and sit on pillows in some shots, or had  Bergman slouch down (as evident when she sits on the couch in the  "franc for your thoughts" scene).
