Doctor Who Series 13: 8 Leaked Details We Already Know

It took a little bit longer than expected, but we can finally say it: Series 13 of Doctor Who is currently being filmed.

Starting in November and with an estimated shoot length of ten months, it's great that the ball is actually rolling, but as of right now, we're in a bit of a weird middle ground in terms of the information that's being provided to us.

On the one hand, it's too early to expect the BBC to open the floodgates on the characters, villains, storylines, and settings we can expect in this upcoming batch of episodes, but on the other... the leaks have started.

Doctor Who is one of those shows where it's nearly impossible to keep a lid on things, especially when it's shooting on location. Its fans are so hungry for details that they're able to sniff things out that the BBC hasn't officially confirmed yet, and Series 13, like every other series before it, has been subject to this same level of scrutiny as of late.

And so, it's a good time to run through some of the leaked information that we've seen so far, from set photos to returning crew members - and even the odd Weeping Angel.

With each new series of Doctor Who comes a brand-new crop of guest stars, a trend that Series 13 will undoubtedly continue.

Across Jodie Whittaker's first two series, the likes of Lee Mack, Chris Noth, Mark Addy, Lenny Henry, Stephen Fry, Art Malik, and James Buckley all played supporting roles in various stories, and it looks like we've just got our first look at one of the guest stars we'll be seeing when Series 13 eventually hits our screens.

In a recent round of set photos snapped by curious fans, comedian John Bishop can be seen stood in the middle of an ordinary Welsh street, hands in his pockets.

In another photo taken at the same location, the Doctor and Yaz can be seen stepping out of the TARDIS, so this might be where Bishop's character first meets the Doctor.

While it's safe to assume that Bishop is merely a one-and-done guest star, there's also some speculation that he might become a more permanent companion, whether that's for three or four episodes, the entire series, or even into Series 14.

Going against this is the fact that he would probably end up being a similar type of character to Bradley Walsh's Graham (one of the companions Bishop would be replacing) in that he's an older gentleman who provides comedic relief.

Then again, Doctor Who consistently has young, contemporary females as companions, so this type of repetition might not be an issue.
