According to Hepburn biographer Alvin H. Marill, Hepburn was very vocal in critiquing the direction of long-time collaborator George Cukor during filming. After Cukor filmed a fire scene, she questioned his handling of the actors, " I don't think they would have to be told about the fire. They would smell the smoke." Cukor finally Spoke up to his star, "It must be wonderful to know all about acting AND all about fires."
