PHOTOS: David Tennant In Doctor Who - The Christmas Invasion #ThrowbackThursday

David Tennant appeared in his first full adventure as the Tenth Doctor in the 2005 Doctor Who Christmas special The Christmas Invasion.

The Christmas Invasion first aired on Christmas Day 2005 at 7pm.

The Christmas Invasion 
Rose and the newly-regenerated Doctor continue their adventures together in this Christmas Special episode. Christmas becomes a time of terror for Planet Earth, as the whole of mankind falls under the shadow of the alien Sycorax. Rose needs the Doctor's help, but can she trust a man with a new face?

The Christmas Invasion was the first Doctor Who episode to premiere on Christmas Day since The Feast Of Steven, part seven of The Daleks' Master Plan (1965). It was also the first episode to premiere on a Sunday

The episode was mostly filmed in Cardiff, but the scenes on the Sycorax ship were filmed at Clearwell Caves in Gloucestershire. The name 'Sycorax' is the name Shakespeare gave to the unseen witch, the mother of Caliban, in the play The Tempest, and a scene in the series 3 episode The Shakespeare Code has the Bard hearing the name from the Doctor himself. 

The Doctor's right hand is severed during the swordfight with the Sycorax leader, revealing the Time Lord ability of fully restoring damage to their new bodies within fifteen hours of their latest regeneration cycle. The severed hand became part of a story arc across spin-off series Torchwood, returning to the TARDIS with Captain Jack in Series Three's Utopia before generating the Metacrisis Doctor in Series Four finale Journey's End.

The Christmas Invasion saw the David Tennant and Billie Piper joined by series regulars Noel Clarke as Mickey Smith and Camille Coduri as Jackie Tyler. The episode also featured Penelope Wilton as Harriet Jones, first met as the MP of a tiny constituency in Aliens Of London and now serving as the Prime Minister of the United Kingdom.

The episode was written by Russell T. Davies and directed by James Hawes. Music was written by Murray Gold, including the specially composed Song For Ten.
