'Mask', the film about the teenager 'Rocky' with a leonine facial disfigurement, the one with Eric Stoltz and Cher. Rocky, who had already exceeded his life expectancy, had a map on his bedroom wall and his ambition was travel the world, sticking flags in his map to mark where he had been. The morning that his mother goes into his room and realises the inevitable has finally happened, instead of the usual wailing and weeping you would expect she instead starts sticking flags randomly into his map, saying something like "now you can go anywhere you want in the world".
I haven't seen the film for nearly 20 years, but that was such an understated and thus powerfully poignant scene of grief reaction that it has stuck with me ever since. Cher really proved her acting ability here for the first time I think.
