I rented the 1985 PBS version over the weekend and
It had none of the fantasy elements of the film. It was just a couple of kids (who are terrible actors, btw) building a fort in the woods.
It was really short too, less than an hour. The acting was horrible and the music sucked. It was like watching "a very special" afterschool special.
Though it did have a very young Annette O'Toole in it, playing the teacher.
Rent the movie. Forget about the PBS version.
