And here are some big whopping details for this year's Christmas special. Well, we still need a title for it.
First thing is first - this one is set during World War 2 and Claire Skinner is playing a widowed mother named Madge Arwell, that ends up in Dorset with her children, Lily and Cyril and embarks on an unforgettable adventure with a mysterious bowtie wearing man named the Doctor. Also appearing in the special are Bill Bailey, Alexander Armstrong and Arabella Weir and the press for this special episode does seem to indicate this year's special really is the show's take on The Lion, The Witch And The Wardrobe.
However two other guest stars that will also be appearing in this episode are Karen Gillan and Arthur Darvill. On Saturday last, a scene was filmed where the Doctor paid Amy and Rory a brief visit for New Year's, so while it's likely that their days travelling with the Doctor really are over, Amy and Rory still aren't forgotten either. The episode (yet to be titled) will be written by Steven Moffat and directed by Farren Blackburn.
