There’s a scene that in Atom Egoyan’s 1997 Cannes Grand Prix winner The Sweet Hereafter where a camera soars into the sky to watch as a bus glides down a windy, remote highway in Canada filled with children. The bus is about to crash and kill many of them, an unimaginable tragedy. But in the moment, the viewer is transported; it’s a beautiful shot, one of many in the film, and one that in simple lyric imagery conveys the context for the rest of the film.
