Slasher: L'Ascension et le Déclin

This is a pretty good treatment of the thinking that went on behind the scenes of movies like "Prom Night", "Friday the 13th", "Nightmare on Elm Street", "Texas Chainsaw Massacre", and others. The great thing is that the cool stories and insights are told by the key players involved (directors, producers, special effects artists). You get to hear not only their thoughts on the psychology involved, but also about the marketing struggles they had to deal with.

Essentially, this is a documentary which interweaves present-day interviews with film clips from classic 80's horror flicks to give you a behind the scenes look at a genre during its peak period of interest. If you're a horror fan, you'll probably like watching this.
