Inside the magazine there is a six page feature on the show, including interviews with the show's outgoing lead writer Steven Moffat, alternative first Doctor David Bradley, plus an item on Radio Times coverage of the twelfth Doctor's era over the last few years.
Speaking about the arrival of the new Doctor in the form of Jodie Whitaker, Moffat explained why casting a woman hadn't occured when he first took over, even though he had previously introduced a female Doctor in the form of Joanna Lumley in The Curse of Fatal Death:
If we’d replaced David Tennant with a woman it wouldn’t have worked. It was too early. We could have replaced Matt Smith with a woman, given that his Doctor was more sexless and less of a lad, but then I got obsessed with seeing Peter in the Tardis.Bradley thinks she is a good casting choice:
When I heard it was Jodie I thought, "Well, that's perfect" - because she's got the range and she's funny. They just need to keep that sense of fun and not forget the comic energy.
You can read the full interviews in the Radio Times, on general release in the United Kingdom tomorrow, 2nd December.
The 'legendary' Christmas edition of the Radio Times (23rd December - 5th January) will of course feature Twice Upon A Time, and will be on sale from Saturday 9th December in London and the South East, and nationwide by Tuesday 12th December.
