According to Georgine Darcy, the scene in which the man and woman on the fire escape struggle in their attempt to get in out of the rain can be attributed to a prank by Sir Alfred Hitchcock. Each actor and actress in the apartment complex facing Jeff's rear window wore an earpiece through which they could receive Hitchcock's directions. Hitchcock told the man to pull the mattress in one direction and told the woman to pull in the opposite direction. Unaware that they had received conflicting directions, the couple began to fight and struggle to get the mattress inside once the crew began filming the scene. The resulting mayhem in which one of the couple is tossed inside the window with the mattress provided humor and a sense of authenticity to the scene which Hitchcock liked. He was so pleased with the result, that he did not order another take.
