It’s such a repository of British acting talent - so many familiar faces pop up. I reckon the likelihood of some of the boys in the team showing up in classic Who roles like the 2IC on a space station is pretty high into the future.

I could see Hannah Waddingham doing a fantastic turn as an antagonist either as a one-off or across a season - I’m quite surprised she hasn’t popped up already!

Roy Kent has also made an appearance, as has Doctor Sharon.

Brett Goldstein was in Jodie Whittaker-era Who and Sarah Niles was in one of the most iconic Tennant-era episodes where she’s one of the interfaces in the library where we first encounter River Song.
