Could Richard Clark be the most generous director when it comes to teasing the fans? If not, he is certainly in the running.
Over the last few days he has tweeted some more about the goings on on set, and even more about the mysterious 'Bob'.
Tweet 1 - More of the same today. ‘Bob’ wielding his weapon as the forces of darkness close in. All hope lost..
Tweet 2 - Well that was one hell of a day. Now standing in the set for the next ep. Absolutely brilliant. The art dept have worked miracles.
Tweet 3 - A days filming free of stunts, monsters, mayhem and madness. It’s barely Dr Who at all. Although there is of course a giant foot.
