ENDING SPOILERS - In some versions, the final shot, where everyone dies, lasts until the film runs out of the camera, which leaves a blank white screen after the film slips out of the camera's gate. In other versions, there is a dissolve between the the final shot and the blank screen at a much sooner point--and the viewer does not see the film slip out of the gate. The Criterion Collection edition released in 2002 has the latter version of the final shot.
