Benedict Cumberbatch is way too successful now to be the Doctor, anyway. He's reached the "playing the villain in Hollywood blockbusters" level of fame which is pretty much as high as a british actor can go.

I don't think he'd be a very good fit, he's really great at playing the straight man, but the Doctor needs to be the crazy one. I could see Martin Freeman being a great companion, but that's basically what he's doing in Sherlock already.

I read that he was basically in second place last time around, he was going to be the next Doctor until Matt Smith auditioned. I'm not sure if that would make him more or less likely this time around.

I'm pretty sure Ejiofor is getting too successful to be called back to Who, he's starring in movies and things now. Personally, I'm hoping for Adrian Lester or Paterson Joseph.

Yeah, I was wondering if they're just going to make her go insane over all this. The hallucinating and the holes, and the fact that she's ingested an awful lot of powerful mind bending potions, maybe she's just going to go completely crazy and they'll make Nick deal with that now. After all this I seriously doubt his…
