Syfy celebrates holiday season with 20th annual New Year's Eve 'Twilight Zone' marathon

Also, original movie "Christmas Icetastrophe"

Syfy will celebrate the holiday season with the original movie "Christmas Icetastrophe," a Christmas Day disaster film marathon, and the 20th annual New Year's Eve celebration of Rod Serling's legendary series "The Twilight Zone," which will take viewers into a dimension as vast as space and as timeless as infinity.

Among the iconic episodes airing during this year's marathon will be "Nightmare at 20,000 Feet," "To Serve Man," "Time Enough at Last" and "Eye of the Beholder."

Syfy began transporting viewers into that middle ground between science and superstition Dec. 31, 1995.

In "Christmas Icetastrophe," premiering Saturday, Dec. 20 (9 p.m. ET/PT), an asteroid strikes a small town preparing for Christmas, triggering an explosive wave of ice crystals that threatens to freeze all life on Earth. The movie stars Victor Webster ("Continuum"), Jennifer Spence ("Stargate Universe") and Richard Harmon ("Bates Motel").

The holiday programming festival heats up Christmas Day with a full day of cold weather-themed movies.

Syfy will close out 2014 with "The Twilight Zone" marathon, which runs Wednesday, Dec. 31, from 8 a.m. until 5 a.m., concluding Thursday, Jan. 1, from 6 a.m. until 6 a.m.
