On Golden Pond (1981)

Continuity mistake: When the boy is dropped off at the cabin, Ethel's sweater is zipped down. It goes to a close-up of her and the zipper is up. In the next shot, the zipper is down again.

Billy Ray: So, I heard you turned 80 today.
Norman: Is that what you heard?
Billy Ray: Yeah. Man, that's really old.
Norman: You should meet my father.
Billy Ray: Your father's still alive?
Norman: No, but you should meet him.

Trivia: Henry Fonda won the Best Actor Academy Award for his role of Norman Thayer. At the age of 76, Fonda became the oldest winner in the Best Actor category in Academy history (his record was broken in 2021 by Anthony Hopkins, who won at 83).
