Shadows', the mid 70s series of supernatural tales for children, 'Dark Encounter' is an interesting addition to one of the YA cornerstones of Wyrd Britain fiction. Written by Susan Cooper what we have here is a short tale that seems to exist in the same storyworld as her 'The Dark is Rising' novels.
The story tells of an actor (Alex Scott) returning to the town where he was evacuated to during WWII and where he meets a quartet of unusual folks (including Brian Glover) in an old windmill and is made to confront his fears of both trees and 'The Dark'.
There really isn't all that much here; the story is crammed into the limited run time, the effects are entertainingly rudimentary and the acting - with the exception of Shelagh Fraser (Luke Skywalker's Aunt Beru) - is very overdone but it makes for an interesting artifact and an intriguing addendum to the novels.
