The story can now be told, Beverly D'Angelo grabbing Chevy's crotch in this scene was improvised
"We had one take left, and it was the end of the day," D’Angelo recalled. "I said, ‘I bet nobody catches this.’ We did the shot, freeze, and I put my hand there. It was like, ‘OK, that’s a wrap. Everybody go home.’ It was subtle. And it had to stay in the film because it was the only shot left! What are they going to do? They didn’t have a choice."
