on the issue of the caption: "John Hurt as the Doctor"... I've deliberately not read any spoilers so may be thinking too hard about this (not something I'm often accused of doing) but it didn't say "John Hurt the next/12th/new Doctor" so does that mean we shouldn't assume he's going to be the *actual* doctor???

and someting that's bothered me for ages: remember a couple of series ago when the TARDIS exploded, causing the tear in space/time, and there was only river/rory/amy/the doc/a dalek left in that museum. at the end the doc says that he doesn't know why the TARDIS exploded in the first place and i assumed this was going to be addressed later, but I don't think it was.

do we know why the TARDIS exploded?

no I don't McNewbie - I think that John Hurt may feature as an older Dr in the 50th anniversary episode:

There is a lot of speculation that he might be the time war dr.. Somewhere before new who era

He's the Valeyard. Possibly.

The Silence blew up the TARDIS. Probably.

(Foolishly thinking that to do so would only kill the Doctor and not actually blow up the universe.)

Right, so that's that all covered.

Not sure how Saturday nights are going to be spent until November though
