Possible spoilers for the Dr, Who 50th anniversary special ahead.
Proceed with caution.
So if you are still reading, then be ready for a huge announcement that appears to not be authorized by the BBC.
In a recent interview Tom Baker straight out said he was going to be in 'The Day of the Doctor'.
That really leaves the it open for the possibility of any of the other past Doctors to be in it. I am sure there are sill many surprises yet to come.
Just four more days to go.
