Outpost Gallifrey has learned the specifics of the Children in Need Doctor Who special airing next week. The special mini-episode is actually 3 and 1/2 minutes long, and will begin at exactly 9:06pm during the telethon (though of course there is always room for slight variation in the timing). Additionally, we've learned that K9 will be in the studio joining the presenters for the evening. As always, this information is subject to change up to air time!
BBC Radio Jersey recently interviewed the director of the special, who said it's set immediately after the end of The Parting of the Ways, is set in the TARDIS, and is "a real episode that links the last series to the new one and is part of Series Two." The interviewer on Radio Jersey said they filmed it only in the last two weeks in Cardiff: "So I don't know what’s in it, I don't know how long it is but I do know it's a scene between Billie Piper in the TARDIS and it's the moment David Tennant materialised at the end of the last series."
