Spoilers abound from here on out, so this is your last chance to stay unaware.

We’ve already reported that Mark Gatiss is to write two episodes for Doctor Who and here’s some info on one of them. The third episode of the series, it’s rumoured to be called Robots of Sherwood and feature Tom Riley and Ian Hallard. Hallard’s character is apparently Alan-a-dale, one of the Merry Men.

Riley had this to say on twitter:

Well that’s out then. I’ve been a massive fan since I was even smaller than Jenna. Very excited. @Markgatiss‘s script is awesome. #DoctorWho
