Ooh what a scary poster of a moment that doesn’t occur in the film at all! In this picture a bunch of british WW2 orphans are shipped off to the dumbest possible location for an orphanage, and then ghost stuff starts happening. Probably. The film could really use a flashlight, or a full moon, anything that emits light.

Small point, but a lot of children were evacuated from the major cities to protect them from bombing, so most of the children wouldn’t be orphans.
