Doctor Who confirms series 13 Comic-Con panel and teases "very special surprise guest"

And the quartet will also be joined by a "very special surprise guest", whose identity is yet to be revealed.

Presumably, that special guest will be someone else who will play a part in the upcoming series 13, for which a fuller cast has yet not been revealed, with some fans guessing Sacha Dhawan could be set to reprise his role as The Master.

Of course, it could also be a brand new character who we haven't yet been told about, or perhaps a fan favourite from years gone by, such as River Song, with star Alex Kingston having previously said she'd love to return to the show to appear alongside Whittaker.

The panel will likely include some discussion about the upcoming series, which is confirmed to debut later in 2021, although no exact date has been unveiled.

There will be only eight episodes in Doctor Who series 13, three less than usual, in a move that allows the show to stick to its usual production cycle despite complicated new health and safety guidelines.

There have been some rumours that Whittaker could be set to leave the series after the upcoming run, although this has not been confirmed yet and reports linking It's A Sin star Olly Alexander have been dismissed by the actor and singer's agent.

A BBC insider told RadioTimes.com last month: "As ever bosses are staying tight-lipped about what they have planned – but with filming still going on they clearly have plans for episodes to be playing out much later into 2022, so there’s lots more to come for Jodie’s Doctor."
