A video interview that David Tennant had at ComicCon in 2009 has come to light so that's the David Tennant Treat 4 Today Updated 20/9/10

David Tennant made an appearance on the Doctor Who panel at ComicCon in San Diego, California on Sunday 26th July between 10am and 11am. All tickets for ComicCon were already sold before David Tennant was announced. Tickets did not guarantee entry into the DW panel so people had to queue on the day to get in. David was only be on the panel and not signing autographs afterwards.

People can post questions in the comments section of this page on the Los Angeles Times website and some of the questions will be asked during the panel.
There are RUMOURS that a Doctor Who movie could be announced at ComicCon. Russell T Davies has denied reports that he is working on any DW movie. The BBC said in a press release that they are "developing a film script" but filming any movie would still be a long way off, although that hasn't stopped people on the Internet saying that it is actually going ahead! David Tennant said at ComicCon on 25/7 that there will be NO Doctor Who movie announcement at the panel. Updated 26/7
