Richard Matheson’s influence on fantasy and horror in the last half of the 20th century is immeasurable. As a novelist and screenwriter, he wrote tales of ordinary people encountering the unknown, and brought the musty vampires, witches and shambling dead of the Victorian era snapping and snarling into suburban row houses and two-car garages. But Matheson’s prolificacy also extended to the non-fantastic — Westerns, war stories and crime suspense. Leave it to Cult Fiction Underground head honcho Bob Slendorn to devise a hard-hitting tribute to the recently departed master writer. It drops on the Cult Fiction Underground this weekend with the Terence Young-directed Charles Bronson vehicle Cold Sweat, based on Matheson’s 1959 novel Ride the Nightmare. This tale of a family man with a very dark secret features a stellar supporting cast that includes James Mason, Liv Ullmann, Jill Ireland and French voice actor extraordinaire Jean Topart in a rare onscreen appearance. Don’t miss it.
