How is it different from the movie.
Did you end up reading the book?
Presumably the OP meant a novelisation.
Must be more intense.
I've never seen a novelization for Prom Night.
There's a book?
All movies pre-85 or so had novelizations. It was all people had to re-experience movies at will before VCRs were widely available.
I remember there were novelisations for a lot of movies back then, but I've never seen one for this.
