This Halloween, make sure your costume is completely safe...and totally un-fun! From Centron films in 1977, filmed on location in Lawrence, Kansas.
You can get all the details on this film from Jason at Scar Stuff - who has a starring role (14 seconds!) as one of the kids in the film.
Fun tip: Play both videos simultaneously. It turns the soothing narrator's voice into something a bit more sinister (yet surprisingly not jarring - she's just that pleasant).
