Peter Capaldi may have announced he’s leaving after the next series of Doctor Who but he’s not gone just yet.

The cast and crew of Doctor Who were out in Cardiff on Sunday filming for series 10 of the show, which starts later this year.

And it appears there’s a creepy new villain to worry about.

Keen fans who were watching the filming take place managed to see some of the stars in action, as well as getting a close up of the new villains.

Peter Capaldi, new companion Pearl Mackie (who’ll be playing Bill), and returning companion Matt Lucas were spotted on site, while there were two of the new monsters also on location.

The pair, who were draped in red robes and have stony-looking faces, seem to be similar in appearance to a character who appeared in a series four episode, The Fires of Pompeii.

In that 2008 episode, which also starred Peter Capaldi and former companion Karen Gillan before they were cast as the Doctor and Amy Pond, the High Priestess of the Sibylline Sisterhood was one of the villains – and she looks remarkably similar to these new creepy cloaked creatures.

The filming, which took place in Cardiff Bay, shows two of the red cloaked figures being attacked by people dressed in overalls.

This will be Peter Capaldi’s final series as the iconic Time Lord, and the show is set to return for its tenth series on April 15 2017.

There was also the reappearance of the “truth” sign that had been seen at earlier previous filming locations.

This symbol raises a few questions about the series.

Firstly, and quite obviously, what is “truth”?

Or could it just be part of a single storyline?
