BBC teases “Iconic star” Reveal
They teased the announcement via their twitter page:
“Casting news! An iconic star will be appearing in #DoctorWho and we’ve been granted permission to reveal who at midnight… See you at 00:00!”
With the Christmas special readthrough last week (draft script pictured), it seems likely that, whoever it is, they will be appearing in the festive special as filming begins shortly.
