 Director Milos Forman (qv) relied heavily on reaction shots to  pull more characters into scenes. In some group therapy scenes,  there were ten minutes of Jack Nicholson (qv)s reactions filmed  even if he had very little dialogue. The shot of  Louise Fletcher (qv) looking icily at Nicholson after he returns  from shock therapy was actually her irritated reaction to a piece of  direction from Forman.
