The well-respected Doctor Who fansite Blogtor Who published, just minutes ago, a compilation of rumours regarding next year's 50th anniversary special. And then pretty much immediately deleted them.
But I have them all here, so let's take a look.
Blogtor cite "trusted people (with no reason to lie)" in providing all of the following info.
They say that the show will be called The Eleven Doctors and, indeed, feature all eleven doctors. They stress that all of them have agreed to take part, even marking all in bold – which is odd, as not all eleven are alive. Perhaps they mean there are agreements in place to somehow feature all eleven?
The rumours go on, and Blogtor say that two script variants were being prepared, one to feature Christopher Eccleston more heavily than the other, dependent on how much he wants to be involved.
It's said that show is to run for ninety minutes and will start shooting in February – while Mark Gatiss' drama about the creation of the show is said to start shooting in January.
It is pretty clearly implied that these pieces of info were all corroborated by secondary or multiple sources as the story also said:
Series 7 Part 2 (8 episodes airing in Spring 2013) will lead into the 50th Anniversary with appearances from past Doctors in some stories. [I should add, I've only heard this from one person and, personally, I'm not too sure of its veracity. Included for completion.]
The rumours don't actually stop with the 50th anniversary special either, as these unnamed sources have apparently also revealed that Matt Smith is set to regenerate in a subsequent special set for New Year airing – presumably the 2013-14 New Year.
Now, this post was deleted pretty quickly, and I have no idea why. Still, it was out there for a while…
