When Harry Met Sally (1989)

Continuity mistake: During the first car ride scene Harry is spitting the seeds out the window. One of the shots shown of the car from the outside shows the window still up after he has rolled it down.

Sally Albright: At least I got the apartment.
Harry Burns: That's what everyone says. But, really, what's so hard about finding an apartment? What you do is look in the obituary section. You see who died, find out where they lived, and tip the doorman. What they could do to make it easier is combine the two. You know, Mr. Kline died yesterday, leaving behind a wife, two children, and a spacious three bedroom apartment with a wood burning fireplace.

Trivia: When they are in the museum and Harry says "For the rest of the day, we are going to talk like this...", the last thing he says is ad libbed. "But I would be proud to partake of your pecan pie." is not in the script. You can see Meg Ryan look off-camera at the director and say "Oh, no" but she continues with him. It's obvious that she wasn't expecting it. [This is confirmed as true in the documentary on the DVD.]
