The Office Christmas episodes brought the series to an end

The very first shows of the comedy series The Office felt a little strained, a little forced, but by the time these final specials were shown it was perfect and quite choking.

This single-disc DVD has the Christmas editions, absolutely the bleakest and most painful festive comedy you've seen, and yet also the most joyous.

Eventually. There are fewer extras than on the series DVDs but we do get a commentary by writers and directors Ricky Gervais and Stephen Merchant.

There's a half-hour documentary about the series that's clip-laden but good.

Lastly, there's a Making Of about filming David Brent's Freelove Freeway song and the full, glorious, awful video for If You Don't Know Me By Now.

Troy

Homer's Illiad comes to DVD, or about half of it and then from a distorted Hollywood perspective. But it's so epic, it has to be a two-disc set.

Except that you'll wonder if Warners has a stash of blank DVDs it's trying to get through: the extras are fine but do not need a disc of their own.

Homer's Illiad was given the Hollywood epic treatment

Diane Kruger's face launches a thousand ships and that fleet looks incredible: every visual in the film is staggeringly impressive.

Few of the actors are. But as sheer spectacle, it's unbeatable.

The extras could easily be beaten and you have to wonder if one day we'll get a three-disc special edition with a better selection.

But for now, we get a pair of featurettes about the visual effects of the film and one about building the sets of ancient Troy.

Big Train: Series One and Two

It was never a great success on TV - which is presumably why the whole lot is being released on one DVD instead of two separate ones, months apart.

Yet watching it now it's hard to see how it could possibly have gone wrong: this is a very funny sketch show from the makers of Father Ted.

It also stars people you'd have to pay a fortune to hire now: Simon Pegg, Julia Davis, Catherine Tate and more.

Still, it's also hard to understand how the running gag of a staring contest can be so funny. But it is.
