Voyage dans l'inconnu: Les Forces du diable

I still remember this creepy movie. It was creepy in a subtle sort of way like most episodes of Kolchak, The Night Stalker. I wasn't very sophisticated as a child but I think this must have been something for me to remember it all these years later. If anyone knows where you can get it on VHS, I would be interested in seeing if it were still as disturbing after all these years.
