Producer Heather Challands said: "This production has me very excited. Not only do we have the return of Katy Manning as the amazing Jo Jones alongside Tim as the Doctor, but we also have the Mondasian Cybermen.

"Stewart and Lauren have written a terrifying, gothic script that goes from a Victorian House on an alien wasteland to the depths of Mondas. The Doctor and Jo come across the Pepperdine family, who are hiding quite a few secrets, but even they don't know the true extent of the danger they are in."

Actor Tim Treloar said: "It's always great fun to be back doing a Third Doctor story, and this a brilliant one - very ethereal and atmospheric. It's something new for the Third Doctor Adventures to have the Doctor and Jo outnumbered by a family unit, and the Cybermen are my favourite Doctor Who baddie."

His co-star Katy Manning added: "Tim and I had a wonderful time together in this very different story, with a lovely script by two writers I haven't worked with before. There are a lot of very strange goings on for Jo in this, but she's a tough little cookie! It was really quite incredible to perform.

"From the second I met Tim, I had that same kind of rapport that I got when I first met Jon. What Tim's brought to it is not just an impersonation - he's doing a very good Jon Pertwee, but there's also that camaraderie, that naughty giggly thing, and that's what comes across to people listening."
