If all the pre-Christmas cheer is getting a bit much for you, then the new Black Mirror special from Charlie Brooker is essential viewing - a tech horror story in three acts, 'White Christmas' explores the dark side of Yuletide.
Brooker, though, insists that the decidedly un-festive special is not intended as a riposte to traditional Christmas programming - even if he objects to the manner in which certain parties exploit sentimentality at this time of year.
"I think it's f**king incredible that a f**king supermarket has turned the First World War into an advert for a f**king chocolate bar - I think it's staggering," he begins.
"Having said that, I quite like Christmas specials - but I missed the tradition of having ghost stories at Christmas.
"It felt like if we were going to be doing a big one-off Black Mirror then Christmas was a good fit for it - more so than Halloween. For me, it's a more evocative time and it gives us a slightly different spin on things."
Both Brooker and 'White Christmas' star Rafe Spall agree that there's a tradition of slightly gloomy drama in the dying days of the year.
"If you think about something like The Snowman, there's a melancholy and a strangeness to it," suggests Spall.
"...and EastEnders at Christmas is never cheerful or feel-good," Brooker adds. "It's basically kittens being thrown into a cement mixer for an hour."
Spall accepted a part in Black Mirror without having ever seen the series, but having once read a script for a previous episode, the Get Santa star says he "knew the world" he was going into.
"But it was the quality and originality of the writing [that appealed]," he explains. "It truly is wholly original and that's a rare thing to come across in this industry."
Hamm's involvement in 'White Christmas' is described by Brooker as "fortuitous" - the Mad Men star sought out the writer on a previous trip to the UK after becoming obsessed with his BAFTA-nominated series.
"I'd seen both previous series and absolutely loved it," Hamm reveals. "I mean, no-one in the States had seen it when I came over here to shoot it. No-one knew what I was talking about.
"Now I have studio executives saying, 'Oh my God, have you seen this show?' - it really reached some sort of tipping point."
Black Mirror looks set to continue doing that for some time to come - with more episodes lined up to follow the 90-minute 'White Christmas'.
"Luckily the world is so horrible..." Brooker concludes, "...that there's constant inspiration."
Black Mirror: White Christmas airs on Tuesday (December 16) at 9pm on Channel 4.
