Details of Doctor Who‘s upcoming 13th season were revealed during the Comic-Con@Home virtual panel this morning, including two new cast members and a radical shake-up to the show’s traditional format.

Showrunner Chris Chibnall and stars Jodie Whittaker and Mandip Gill were joined on the panel by British comedian and actor John Bishop, who will play new companion Dan, filling the gap left by the departure of Ryan (Tosin Cole) and Graham (Bradley Walsh).

“If I could tell my younger self that one day I would be asked to step onboard the TARDIS, I would never have believed it,” said Bishop. “It’s an absolute dream come true to be joining Doctor Who, and I couldn’t wish for better company than Jodie and Mandip.”

Also joining the cast for the thirteenth season is Jacob Anderson, better known to Game of Thrones fans as Grey Worm, who will play a recurring character called Vinder.

“The Doctor has been a part of my life forever, from watching and rewatching the serials on VHS as a kid and being terrified, to unexpectedly finding my eyes watering when the Tenth Doctor said ‘I don’t want to go’, I always wanted to live in the Whoniverse,” said Anderson. “Not only has a lifelong dream of mine now been fulfilled but to be playing a character as fun, adventurous and dynamic as Vinder is the cherry on top. This is very cool.”

While plot details and news of any returning monsters were kept under wraps, Chibnall has confirmed that season thirteen will be one continuous, epic story.

“Every episode is a chapter in a bigger story,” he says. “We’re going to go to have all kinds of characters and monsters, and it’s all going to be part of a bigger whole. It’s definitely the most ambitious thing we’ve done since we’ve been on the series.”

A date for the season 13 premiere is yet to be announced, but it’s expected to air sometime later in 2021.
