Newark, NJ & Los Angeles, CA, November 3, 2004 – IDT Entertainment’s New Arc Entertainment has joined with Industry Entertainment and Nice Guy Productions to produce Masters of Horror, an anthology series that assembles such prominent genre directors as John Carpenter (Halloween, The Thing), Don Coscarelli (Phantasm, Bubba Ho-Tep), Joe Dante (The Howling, Gremlins), Mick Garris (Riding the Bullet, The Stand), Stuart Gordon (The Re-Animator), Tobe Hooper (Texas Chainsaw Massacre, Poltergeist), John Landis (An American Werewolf in London) and George Romero (Night of the Living Dead, Dawn of the Dead), for a minimum of 13 one-hour films.

IDT Entertainment Sales will handle worldwide distribution of the Masters of Horror series and Anchor Bay Entertainment will handle all video releases. The series will make its debut at American Film Market (AFM) 2004 in Santa Monica, CA.

While some of the Masters will be directing from their own screenplays, an equally impressive roster of writers will be participating in the anthology, including Richard C. Matheson (What Dreams May Come, Somewhere in Time), celebrated horror comic book creator/writer Steve Niles (Hyde, 30 Days of Night), noted horror writer David Schow (A Nightmare on Elm Street 5: The Dream Child, Bullets of Rain) and Michael Brandt and Derek Haas (2 Fast 2 Furious, Catch That Kid). In addition, writer Kim Henkel and Tobe Hooper will collaborate for the first time since “Texas Chainsaw Massacre.”

Masters of Horror grew out of an informal bi-monthly dinner attended by several of the horror genre’s most highly regarded directors. The filmmakers agreed that the short-form anthology approach would serve as an effective way to spin their dark tales they’ve always most wanted to tell.

“Ever since we first brought the project to their attention, IDT Entertainment’s New Arc Entertainment and IDT Entertainment Sales have been extremely supportive of Masters of Horror. As a result of IDT Entertainment’s enthusiastic support, creative input and distribution prowess, we can look forward to a successful launch of Masters of Horror in the U.S. and throughout the world,” said Andrew Deane, Partner, Industry Entertainment.

“For its high profile directors, writers and producers, Masters of Horror is a labor of love, which oftentimes results in productions that go on to become instant classics,” said John Hyde, COO of IDT Entertainment “We are proud to house Masters of Horror within our prolific IDT Entertainment companies. At the same time, we are delighted to work alongside Industry Entertainment and Nice Guy Productions as we enter the production phase of this exciting project.”

Serving as Executive Producers of Masters of Horror are Mick Garris, Andrew Deane and Keith Addis. Principal photography for the first film production is scheduled to begin in Vancouver on March 15, 2005.

New Arc Entertainment, IDT Entertainment Sales and Anchor Bay Entertainment are units of IDT Entertainment.
