For those of you lucky enough to be spending the holidays in Greenwich Mean Time, Christmas comes early tonight with the premiere of Black Mirror: White Christmas on Channel 4. The special holiday installment of Charlie Brooker's "information age Twilight Zone" marks the end of a nearly two-year hiatus since the last episode, "The Waldo Moment." (It will air on December 25th on DirecTV here in the States.)

Here's a sneak peek of Jon Hamm, looking very Season 4 Don Draper, explaining to Rafe Spall how his wife "blocked" him, and we don't just mean on Snapchat. Betty Draper, you were clearly born in the wrong century.
