This isn’t from a movie, but it was really funny. If anyone watches soaps on abc, this was on One Life to Live at Asa’s (faked his own death) funeral. Well Asa is one of the charcters that has been married like 9 times or so. So all of the ex-wives were there at his funeral. They showed each one sitting in the funeral reminicsing about their wedding to Asa, and showed the original clips of the weddings. I think these were really mostly the same actresses too. One of the ex-wives, who is also still a main character on the soap, was played by a different actress during the time she and Asa were married. Anyway, the funny part is, it shows Blair (the current one) remembering her wedding to Asa, they show a flashback clip of it and it is of course the other actress. The “old” Blair is asian, or at least has very dark hair and very different more exotic features that the current blonde haired, blue eyed Blair. So when current Blair snaps out of the little fanatsy, it shows her sitting there, at the funeral with a perplexed look on her face and she whips out a little cosmetic mirror and looks in it, only to look slightly more confused, but then sort of shrugs it off. Very funny to see that the people who write this stuff making fun of how goofy it is that the actors change and no one “in soap land” ever notices the sudden complete change this “soap person” has gone through.
Oh and the part in “Big Trouble in Little China” that someone else mentioned, I found that really funny too. He is looking all tough, but for the lipstick smeared on his face.
