Creepshow (1982)
While there had been two films based on the old EC comics produced by Amicus, this was the first film to really capture the spirit of those 1950s terror tales. While the stories were originals by Stephen King, and not based on particular stories from the comics, this film was almost a dry run for HBO's popular Tales From The Crypt. It was also a refreshing break from the slasher films that dominated the era.
We also got one of the coolest movie tie-ins ever, an EC style comic written by King, illustrated by the great Berni Wrightson, and with a cover by EC's Jack Kamen!
