At 67 minutes and 13 seconds into the first Spider-man movie (just after the Green Goblin shows up at the festival and starts blowing stuff up) there is a kilted man running on the right side of the screen, just as he disapears, another kilted man can be seen running from the right side of the screen to the left. (This is while Peter Parker is tearing open his shirt in homage to the 1978 Superman movie)
Then, when the kid is just standing there waiting for the piece of stage to crush him, there is a kilted man holding a balloon behind him.

Increadibly brief, yes, but it is a BIG Hollywood movie with kilts in it!
