John Carpenter's Cigarette Burns is a grim trip!

It's an episode from the Masters of Horror anthology about a desperate man hired by a rich eccentric film collector to find a notorious rare film called La Fin Absolue du Monde said to have caused a violent riot during its initial showing.

Takes a little while to get going, but once going it gets increasingly gruesome.

You can currently watch it on a few different free streaming services, or I'm sure someone's sharing it.
