Doctor Who writer Matthew Graham has described his upcoming episode in the series as “unpleasant”.
Graham, who co-created Life On Mars, has written the two-part story The Rebel Flesh and The Almost People, which begins this Saturday (May 21).
And he has described the story as “epic” and “scary”, saying he would not be surprised if the BBC broadcasts a warning before it.
He told Den Of Geek: “I showed it to my wife the other night and there were a couple of images in it where she went, ‘Actually, that’s quite scary. That’s not very pleasant.’ I also notice that that it’s going out a bit later. I wouldn’t be surprised if they put a warning out beforehand.”
He also expressed his desire to return to the show, saying: “I had such a good time on this run that I would love to come back and do some more. They seem very, very pleased with the episode, so I hope they’d consider asking me back.”
