For Bill Potts’ first proper trip in the TARDIS, the Doctor takes her to Gliese 581 D, a Utopian world with emojibots and bird-like Vardies.
The Pilot, Episode One of Doctor Who Series 10, hasn’t even aired and we’re already looking forward to the second episode, Smile. That’s Doctor Who for you: ever onwards. The BBC has released the official synopsis for the story, which apparently has a duration of 50 minutes. As ever, if you don’t want to know anything about the serial, you’ve come to the wrong place; nonetheless, the following synopsis doesn’t give much away at all. So indulge all you like:

In the far future, at the edge of the galaxy, there is a gleaming, perfect city. This brand new human settlement is said to hold the secret of human happiness – but the only smiles the Doctor and Bill can find are on a pile of grinning skulls.

Something is alive in the walls, and the emojibots are watching from the shadows, as the Doctor and Bill trying to unravel a terrifying mystery…

The Doctor is played by Peter Capaldi, Bill by Pearl Mackie and Nardole by Matt Lucas. Guest-starring Ralph Little.

Directed by Lawrence Gough (Atlantis), Smile is written by Frank Cottrell-Boyce, whose only previous Doctor Who is the divisive In the Forest of the Night (2014). This one is supposed to be more traditional, so should please more of the audience.
Smile airs on Saturday 22nd April on BBC One at 7:20pm.
