In the two towers when Gandalf is running down the moutain with the army of horses and shit and they got some tight music playing, best part of all the lotr movies. Maybe this part isn't 10 secs but in the first matrix the lobby scene was pretty fucking awesome.
The scene in "Teen Wolf" when Styles is driving the truck around the town and Michael J. Fox is on the roof of the truck "wolfed out" dancing like a maniac. I don't think it gets any better than that...
