Lindsay Duncan has been cast as the companion to David Tennant’s Doctor in the second of the Special Doctor Who episodes to be broadcast later this year.
The report in the Daily Record quotes Russell T Davies as saying:
“Lindsay is an incredibly talented actress and I’ve been an admirer of her work for some time.
“We are delighted to announce that she will be joining the team and playing the Doctor’s most strong-minded companion yet.”
She will reportedly play a character called Adelaide, the most strong-minded companion yet.
