Everyone’s talking about: The Downton Abbey Christmas special

Fresh off the back of George Clooney’s baffling appearance in this charity version, there is widespread confusion about whether he’s actually in the Christmas Day special. Well, he’s not.

So what can we expect? Well, according to the Telegraph, a festive dose of the usual heightened melodrama and barbed quips – and cast members have said that it’s heartwarming and without the sudden deaths of previous years. So there you go.
