New actor for The Doctor could be announced next month
The Twelfth Doctor is expected to first appear on screen at the end of the Christmas special, following the regeneration of Matt Smith’s Doctor.
It would be virtually impossible to keep the identity of the new doctor a secret even if the entire set went into lockdown during filming of the Christmas special, a BBC source told RadioTimes.com.
Moffat potentially staying
A BBC source also moved to squash speculation that showrunner Steven Moffat could also be calling it a day, insisting that he has signed up for at least another year.
