I think the custom held on longer in some foreign countries than it did in the US (except for a movie that has people really geeked out like the opening night of a Star Wars movie or something where it might still happen when the opening intro scrolls up the screen). The last movie I saw was Sonic the Hedgehog with my son. If I get to go to a movie any time in the next month, I'm clapping and cheering even if it is something like Sonic the Hedgehog.
