REVEALED: Details of Who's super-secret timey-wime​y Xmas episode

The super-secret timey-wimey details about Doctor Who's upcoming Christmas special episode have finally been revealed—and it turns out our favorite Time Lord is heading back to World War II England.

Below is the official BBC press release for the episode:

Production has started on the 2011 Doctor Who Christmas Special in which the Doctor (Matt Smith) finds himself in war-torn England embarking on a magical and mysterious adventure with a young widow and her two children.

A stellar guest cast including Claire Skinner (Outnumbered), Bill Bailey (Black Books), Arabella Weir (The Fast Show) and Alexander Armstrong (Armstrong & Miller), join Matt Smith in the emotional festive special, packed full of Christmas thrills and chills.

Steven Moffat, Lead Writer and Executive Producer, commented: "The Doctor at Christmas—nothing is more fun to write. Maybe because it's so his kind of day—everything's bright and shiny, everybody's having a laugh, and nobody minds if you wear a really stupid hat. Of all the Doctors, Matt Smith's is the one that was born for this time of year—so it's the best news possible that he's heading back down the chimney."

The special, set during the Second World War, sees Madge Arwell and her two children, Lily and Cyril, evacuated to a draughty old house in Dorset, where the caretaker is a mysterious young man in a bow tie, and a big blue parcel is waiting for them under the tree. They are about to enter a magical new world and learn that a Time Lord never forgets his debts.

Claire Skinner said: "I am thrilled to be in Doctor Who playing Madge who is a bit of super-mum. It's a magical part."

This marks Matt Smith's second outing as the Doctor at Christmas time and will follow hot on the heels of the successful 2011 series, currently airing on BBC One until October.

The Christmas Special was commissioned by Ben Stephenson, Controller, BBC Drama and Danny Cohen, Controller BBC One. Steven Moffat is Lead Writer and Executive Producer with Piers Wenger and Caroline Skinner, also executive producing.

Filming on the Christmas special will continue until mid-October 2011.

First off—the Doctor will be wearing a stupid hat again? If it's anything like the fez (which never fails to make us laugh), we can't wait to see that—and are we going to Narnia?

Second—and we don't know about you—but we kinda get the feeling that Steven Moffat is truly a Second World War aficionado. This will be the third time, since Moffat began his successful run as Who showrunner and main writer, that the Doctor will be travelling back in time to World War II.

The first time was with ''Victory of the Daleks,'' which was written by Sherlock co-creator Mark Gatiss; and the second time was in this season's thrilling episode ''Let's Kill Hitler,'' written by Moffat himself.

And let's not forget that Moffat also penned ''The Empty Child'' and ''The Doctor Dances'' during Who's very first season, when Christopher Eccleston was the Ninth Doctor and Russell T Davies was the current showrunner.

The critically acclaimed two-parter introduced us to Captain Jack Harkness (John Barrowman) when the Doctor and Rose found themselves in war-torn London amid a very scary and mysterious plague that turned people's faces into spooky gas masks. It's also famous for coining one of the chilliest phrases ever uttered on TV: ''Are you my mommy?''

(Making a whopping total of four storylines set in World War II for Moffat since the show's return in 2005.)

So what do you guys think about the BBC's announcement? Are you looking forward to the Doctor Who Christmas special? (And in case you're suddenly feeling overwhelmed by the yuletide spirit, you can still go back to check some of the spoilery filming pics we posted here.)
