Carry on, Doctors

All previous Doctors - and one potential new one - will appear alongside David Tennant in this year's Doctor Who Christmas special. The Daily Mail quotes executive producer Russell T. Davies as saying the appearance (via file footage) of such stars as Tom Baker (right) will be a treat for longtime fans. "It is also nice for the kids to get to grips with the fact that there have been lots of Doctors." Meanwhile, the latest suggestion as to who will take over from David Tennant are David Morrissey (who plays a character called The Doctor in the special, although that could be a red herring), David Walliams, Paterson Joseph, Billie Piper, Tom Ellis and Catherine Zeta-Jones. No mention of Brisbane's David Knijnenburg, who was linked to the role in the Australian media, though.
