There's a Christmas Eve treat for young story-lovers when Doctor Who star David Tennant swaps the Tardis for the Bedtime Story chair and breathes life into the enchanting seasonal tale of The Christmas Bear by Henrietta and Paul Stickland.
It's Christmas Eve and Bear Cub leaves his parents in their den to go out exploring. Falling into a big, bright hole in the snow, Cub finds himself in Santa's workshop and at the start of a wonderful Christmas adventure. From the post room to the wrapping room, Cub is given a whistle-stop tour of the Christmas present process – with a tantalising glimpse of the toy-testing room. But Cub is disappointed when it's time to leave – until Santa gives him the best present of all...
David Tennant reads four more stories during the festive season: How High Is The Sky by Anna Milbourne, illustrated by Serena Riglietti; Small Mouse, Big City by Simon Prescott; Emily Brown And The Elephant Emergency by Cressida Cowell and Neal Layton; and Miki by Stephen Mackey.

David To Guest On Catherine Tate Christmas Special
On ITV1’s This Morning on 23 November, Ben Miller of Armstrong (Sarah Jane Adventures) & Miller let slip that David Tennant plays one of the ghosts in Catherine Tate’s upcoming Christmas Special. He added that David plays the role in the style of Russell Brand.

That takes David’s tally of known Christmas TV appearances up to 6 (Doctor Who/Catherine Tate Show/Hamlet/Never Mind the Buzzcocks/CBeebies/Alan Carr: Chatty Man) and he’ll also dominate the cinema with the release of St Trinian’s 2 plus no doubt a myriad of TV and radio interviews in the lead up to the regeneration.

Many thanks to Dominic May for the above. You can read Dominic's monthly column, Beyond The TARDIS, in Doctor Who Magazine.

The BBC Press Office has the following details on the show:

Catherine Tate - Nan's Christmas Carol

Nan is the star of this year's seasonal special from Catherine Tate.

The festive show sees Nan's acid-tongued insults catch up with her when the ghosts of Christmas past, present and future, along with a dead husband, pay an unexpected visit, in this comic re-telling of Charles Dickens's tale A Christmas Carol.
Is it too late for Nan to swap her Scrooge-like misery for some seasonal goodwill?
The Christmas special sees Mathew Horne return as Nan's grandson, Jamie, and features appearances from special guests including Ben Miller and Only Fools And Horses actor Roger Lloyd Pack.

I didn't even know he wasn't called Doctor Who. .... I thought you're a Mister Who who was a Doctor.
