This was an exclusive Comic Con trailer made especially for the Doctor Who 50th panel, it has not been released in the US.
This world famous international event is an established platform used by all of the major producers. UK fans can look forward to exclusive content over the next few months.
Fans have been generally disappointed this year at the lack of the BBC's celebrations, with lots of small things building up, such as the lack of the 50th trailer, the Series 7 Boxset which is being released more than a month after America's with less content on it, or BBC America's The Doctors' Revisited specials not showing sign of a UK release.
What do you think? Is the issue of the 50th Anniversary trailer being shown at Comic Con important enough to complain? Is the response adequate? Will they follow up with their promise of exclusive content? Are the BBC doing enough to celebrate, or should they do more?
