Doctor Who Series 11: The Witchfinders is the eighth episode

As we previously reported, the episode of Doctor Who Series 11 that Joy Wilkinson wrote is titled The Witchfinders.

Here is the official synopsis and cast list, according to an official BBC press release:

The Doctor, Ryan, Graham and Yaz arrive in 17th century Lancashire and become embroiled in a witch trial, run by the local landowner. As fear stalks the land, the arrival of King James I only serves to intensify the witch hunt. But is there something even more dangerous at work? Can the Doctor and friends keep the people of Bilehurst Cragg safe from all the forces that are massing in the land?

Guest starring Siobhan Finneran and Alan Cumming. Written by Joy Wilkinson. Directed by Sallie Aprahamian.

From the Radio Times listing:

The Doctor and her friends travel back in time to 17th-century Lancashire, where they get mixed up in a witch trial orchestrated by a local landowner. The air of fear sweeping the land is only intensified when King James I himself turns up – but while the king and the locals are gripped by paranoia about hidden evil in their midst, a very real danger lurks close at hand.

The full guest cast list:

Alan Cumming: King James I 
Siobhan Finneran: Becka Savage 
Tilly Steele: Willa Twiston 
Tricia Kelly: Old Mother Twiston 
Stavros Demetraki: Alfonso 
*Julian Kay: Smithy
 
*The Radio Times listing gives the name of the actor playing Smithy as Arthur Kay but a CultBox source at the filming location in Gosport identified the actor as Julian Kay. No casting or talent agency source exists for a screen actor named Arthur Kay.

Julian Kay was spotted in a photograph from Gosport location filming published by The News, Portsmouth.

The Daily Mail covered Monmouth location filming near Treowen Estate.

Another location used for filming The Witchfinders was a wetland area in Cowbridge used for filming a scene depicting the drowning of  accused witches.

Alan Cumming revealed that he will play King James I in an episode of Doctor Who. King James personally supervised the torture of accused witches and wrote Daemonologie, a dissertation on black magic.

Wilkinson previously described the episode she wrote to Doctor Who Magazine as “dark, funny, squelchy”.

Why squelchy? Well, for one thing there was some very muddy location filming, according to director Sallie Aprahamian in Doctor Who Magazine:

“The weather was not kind to us on one of the episodes – howling rain storms, snow, lots of mud and bright sunshine, sometimes within minutes of each other. The cast and crew were amazing, working on through with good humour and craft. That’s how Doctor Whomagic sometimes has to happen.”

And there is a character called a Mud Witch in Aprahamian’s filming block.

The Witchfinders will air on Sunday, November 25, 6:30 p.m. on BBC One and 8:00 p.m. on BBC America.
