I attended "Lords of Time" convention in Melbourne yesterday. Davison, Baker, McCoy and McGann were all in attendance. Each of them was obviously asked about it, and each said they had "no idea". They all said that it's the kind of thing they will find out about at the very last moment possible. Baker candidly said that he really didn't think a multi Doctor story would work very well, not to mention the fact that Baker certainly doesn't look much like his 6th Doctor Self.
McGann on the other hand looks friggin fantastic for a guy who's 54. He looks 40 to me. He could easily play a part in it, and I really hope he does. He also seems like an incredibly nice guy.
From what some of the other guest said (John Leeson was there, Janet Feilding, and Nicholas Briggs) the BBC don't seem to organised about some things. Both Leeson and Briggs spoke about being called in very last minute to do voices (Leeson doing K9 in "School Reunion" was apparently almost an after thought, and Briggs is doing the Ice Warrior voices and recorded those only last week!
Mitty, completely off topic but how was Janet Fielding?
