Then there's the invasion of CIA headquarters by Ethan Hunt's scratch team in Mission: Impossible (1996). In [De Palma's] search for pure cinema, this might be the purest of all. The invasion sequence runs an astonishing eighteen minutes and, as typical of a film's Development section, constitutes almost pure delay. You can imagine doing it in a couple of minutes, or a lot more.
