Nice!
Tennant has confirmed at a US convention that the stuff he and Tate have shot is only a very small cog in the anniversary specials and that other returning actors have largely been shot in studio or in secret so have been able to be kept secret. Big speculation that Paul McGann, Matt Smith and Peter Capaldi are back, as well as Karen Gillan (who seems to have been dropping possible hints of such on Instagram) and John Simm. If this is true, together with the Beep the Meep style madness this could end up putting the 50th to shame (not too difficult).
