I watched a film many years ago. It was black and white and a sceen i remember was of a person walking up a sand dune/grassy hill with a white fence going up it. The person got to the top of the hill then vanished into the earth. What is the name of this film?!!
'Invaders from Mars' I think, but I remember seeing that film in that brilliant vivid 1950s colour. If only the world was that colour back then, but it was probably as dull as it is now.
