One of the fascinating pieces of trivia below is true*, the other is false. Do YOU know which is which?

It’s a Wonderful Life (1946)

1) As Uncle Billy is leaving George’s house drunk, it sounds as if he stumbles over some trash cans on the sidewalk. In fact, a crew member dropped some equipment right after Uncle Billy left the screen. Both actors continued with the scene (“I’m all right, I’m all right!”) and director Frank Capra decided to use it in the final cut. He gave the clumsy stagehand a $10 bonus for “improving the sound.”

2) For the scene that required Donna Reed to throw a rock into the window of the Granville House, Frank Capra hired a marksman to shoot it out for her on cue. To everyone’s amazement, Donna Reed broke the window with true aim and heft without the assistance of the hired marksman. Reed had played baseball in high school and had a strong throwing arm. Feeling slighted, the marksman took aim and cleanly shot off the fingers of Donna Reed’s throwing hand one by one as she attempted to give Jimmy Stewart a high-five. The marksman escaped into the night and was never properly identified, but many believe he was actor Don Knotts. After hospital treatment, Reed managed to finish the picture after Frank Capra glued Vienna sausages onto her hand, which were eaten by the actors who played her children at the wrap party as payment for their services. Months later, Reed had her hand surgically replaced with a corpse’s hand, but the only hand that took to the procedure was the hand of a silverback eastern lowland gorilla, and it had to be put on backwards. From that point on, Reed was always filmed so her right hand was hidden from view, but her baseball career thrived, pitching for the Cincinnati Redlegs from 1949-1958 until she was forced into retirement after the hand rotted completely off and was eaten by the actors who played her children in It’s a Wonderful Life.
