Today, the twenty fifth of December, is Christmas day and I'd like to take this time to wish all of my readers a Merry Christmas. I hope that you all have a great day and enjoy this year's third special episode of Doctor Who when it premieres later tonight in the United Kingdom at 6pm on BBC One. Tonight's festive special is the first part of the 10th Doctor's final adventure, The End of Time, and the episode will premiere in the United States tomorrow on BBC America's channel. It will have an approximate running time of sixty minutes and a further reminder about it's transmission will be posted here on this site soon. As well as appearing in tonight's special episode of Doctor Who, Catherine Tate and David Tennant will also star in 'Nan's Christmas Carol' tonight. The programme has been written by Catherine Tate and it will broadcast later tonight at 10:35pm on BBC One.
