Backstage at Christmas (CON episode)

"" was a special mini-episode of Doctor Who Confidential that was included on the series 1 DVD boxset. It served as a preview for The Christmas Invasion, and was the only behind-the-scenes material about that episode made by the Confidential production team.

It technically did not go out under the Doctor Who Confidential banner, ostensibly because it was a preview of an upcoming episode, rather than a review of an episode that had already been broadcast. However, the episode did have enough commonality with Confidential — including theme music, narrator, and production team — for most to consider it a part of the Confidential series. It was Simon Pegg's final act of narration for the series. David Tennant, having previously narrated the Confidential team's "preview" episode, Doctor Who: A New Dimension, made his first appearance in front of the cameras for the DWC team.

Aspects of production covered
This short episode was somewhat handicapped in terms of what it could reveal about the episode, as it was made available to the public before The Christmas Invasion itself was. Therefore, it focused on three rather insignificant scenes in the accompanying episode: The entire episode was bound together by the general theme of the differing time pressures that a production crew faces on night shoots versus day shoots. It also contrasted the problems of working with large numbers of extras versus the difficulties of setting up shots involving large numbers of potentially dangerous practical effects.

Additional info
Though this episode goes to great lengths to suggest that the production team had only one opportunity to fell the Christmas tree in the open-air market, the later in-vision commentary to The Christmas Invasion, available on the series 2 DVD boxset, contradicts this. Phil Collinson says there that they actually did reset the scene and film it again.
