[Tom] Baker, who famously played the Time Lord from 1974 to 1981, will be reprising the role this April. His Doctor joins the Paternoster Gang as they fight intergalactic crime in the latest entry to the Trespassers series.

He joins the cast made up of Neve McIntosh as great detective Madame Vastra, Catrin Stewart as her spouse Jenny Flint and Dan Starkey as their loyal valet Strax.

McIntosh added: "Acting with Tom Baker has been something I've wanted to do for so long. He was my Doctor growing up, from when I was hiding behind the sofa."

I'm thrilled TBH, I thought the chemistry between McIntosh, Stewart and Starkey made the previous Paternoster Gang sets some of the most campily enjoyable BF work I've heard. Add Tom Baker, even in his old age... Woof, this'll be good!
