A photographer in a wheelchair spies on his neighbors from his Greenwich Village courtyard apartment window, and becomes convinced one of them has committed murder, despite the skepticism of his fashion-model girlfriend.
 
I spy with my little eye...another Alfred Hitchcock classic.
 
Hitchcock's Signature Cameo:  Alfred Hitchcock appears (At around 25 minutes) winding the clock in the songwriter's apartment. The songwriter is Ross Bagdasarian, creator of the original film and recording performers, Alvin and the Chipmunks. (1961: The Alvin Show).
 
FUN FACT:  According to Georgine Darcy, the man and woman on the fire escape struggling to get out of the rain was based on 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 resulting mayhem, in which one of the couple is tossed inside the window with the mattress, provided humor and a sense of authenticity, which Hitchcock liked. He was so pleased with the result that he did not order another take.
