For the first time in a while, Doctor Who will feature a bona-fide TARDIS team when it returns this autumn, with three companions joining Jodie Whittaker's Doctor on her adventures.

Whittaker described the new series as "an ensemble piece" at the show's San Diego Comic-Con panel, with showrunner Chris Chibnall telling Digital Spy that having a trio of new friends for the Doctor was a deliberate decision.

"I love Doctor Who as a big, popular, mainstream, accessible show," Chibnall said. "So I wanted to make sure that every member of the audience felt they had a relatable character, an access point. Hopefully it means that the show can resonate with the broadest possible audience.

"And of course, three companions with the Doctor... we're really going back to 1963 – that's the format of the show! You're not changing the format, that's how it started, really – which I only realised afterwards."

The Doctor's new friends – Chibnall says not calling them "companions" just feels "a bit more natural" but "is in no way a rule or edict from now on" – include Yaz (Mandip Gill), who is "in absolute awe of the Doctor" and Ryan (Tosin Cole), who "challenges the Doctor from time to time, gets it right sometimes, but wrong a lot of the time".

"Ryan's 19, Yaz is 19, and then you've got Graham who's the oldest of the bunch, so we've got different generations, different genders," Cole told us.

"People have an 'in', in three different ways," Gill added. "We all bring something different to the group, with gender, race, everything. And just the personalities of the three characters are very different.

"They each have a very individual voice, where I think certain people will be able to instantly relate to Bradley Walsh's character, instantly relate to Tosin's... and hopefully just love us all!"

Walsh completes the trio as Graham, with Chibnall confirming that he thought of casting the star having worked together on ITV's Law & Order: UK in 2009.

"He's an amazing actor and that's what I learned working with him on Law & Order," he added. "He has an incredible emotional range. He's able to be really funny, and break your heart. And these guys [Gill and Cole] are exactly the same, as is Jodie. It means you have a range of emotional flavours in the show."

Doctor Who dropped its first full trailer at SDCC, while showrunner Chibnall revealed to Digital Spy that the new series will comprise 10 standalone episodes, with no two-part stories.

Doctor Who will return to BBC One this autumn.
