The following promotional synopsis was also forwarded, confirming the appearances of Neve McIntosh and Catrin Stewart as Madame Vastra and Jenny. The episode will also see the first appearance of Jenna-Louise Coleman’s complicated companion since Asylum of the Daleks.
Following the epic mid-season finale, the Doctor gets in the holiday spirit in the all-new Christmas special written by lead writer and executive producer Steven Moffat (Sherlock).
Accompanied by his newest companion, played by Jenna-Louise Coleman, the Doctor’s latest adventure through space and time sees him once again crossing paths with the homo-reptilian Silurian Madame Vastra (Neve McIntosh) and her cohort Jenny (Catrin Stewart).
Once again, BBC America is providing parity with UK fans of Doctor Who, scheduling the Christmas special at 9:00pm ET on December 25th, which the seasonal among you will know as Christmas Day.
