David Tennant reprises his role as the Tenth Doctor as he makes a surprise guest appearance in a specially written sequel for the third series episode Gridlock.
The 11-minute short was written by Russell T. Davies, who joined the live tweet tonight of the two New New York episodes New Earth and Gridlock. The short stars Anna Hope as Novice Hame who, on the last day of her life, is visited by a familiar figure from her past.
The video was produced by Emily Cook of Doctor Who Magazine and was recorded remotely under COVID-19 restrictions. Emily has been behind the Doctor Who: LOCKDOWN tweetalongs which are in aid of The Film and TV Charity's COVID-19 Emergency Relief Fund, supporting the creative community which has been affected by the Coronavirus pandemic.
