These are legitimate set photos & pretty much give away who will be appearing in the finale of Tennant's run as the Doctor, so don't click if you want to remain unspoiled

Can't say I'm too surprised at the return of the Master, it was always telegraphed, even though it pretty much neuters the whole ending of Series 3 & that death scene between the Master & the Doctor! Ace casting with Timothy Dalton though, even if all I see is Skinner from Hot Fuzz

Doctor DooM

Oh wow. I quite like both of those guys who shall remain nameless!

It was obvious that

the Master would return, the final scene was a homage to the ending of Flash Gordon and the return of Ming in the proposed sequel which never happened.

Nice to see

Dalton in it, always thought that he would be a great Doctor so this is the next best thing.

I suppose the big question is: Timothy Dalton's TimeLord character, is he part of a flashback, Time War era scene, or an actual present-day (insofar as is possible) character? I saw some out-there rumours suggesting that Moffat's blank slate would be the reforming of Gallifrey, which would make some sense as there's only so long you can carry the angst arc.

Looking forward to some more homo-erotic Master/Doctor dreams. Hopefully TD will keep himself out of my subconscious though!
