In theory, The IT Crowd came to an end in September when the last-ever episode aired, but it seems Channel 4 just can't bear to let it go.

So, as a Christmas present for all the cult sitcom's fans, the channel is devoting an entire evening to Moss, Roy and Jen.

As well as giving us another chance to see that final episode again, there’s also this brand new behind-the-scenes documentary. As well as hearing from main cast members Richard Ayoade, Chris O’Dowd and Katherine Parkinson, who have all gone on to huge success since the show began, the programme also features interviews with writer Graham Linehan, guest stars Noel Fielding and Matt Berry, and famous fans such as Paul Whitehouse.

Maybe it will also shed some light on what happened with the American remake.

It’s followed by two classic episodes; one voted for by fans, and the other hand-picked by Linehan. Let’s hope he doesn’t have exactly the same taste as the viewers, or we could see the same edition twice. Although Channel 4 could always blame it on a technical error...
