I still remember the sense of joy I had when I heard that David had been asked to play the Doctor. We were all so pleased for him — as we knew how much Doctor Who meant to him. And now David comes full circle, back doing Doctor Who with Big Finish — except that this time he’s playing the Doctor! It’s the same but different — it’s wonderful to have him back.

I’ve enjoyed working with all the Doctors on TV, but David is on the only one I’d known before he became the Doctor. I’d worked with him on our Dalek Empire series for Big Finish and had such fun. So along with the excitement of directing new Tenth Doctor adventures, I’m so happy to be working with an old chum again.

This is one of those dream projects where I’ve spent months pinching myself. I’m covered in bruises. With two major international stars in place, and the legacy of this era of the TV show to live up to, we’ve worked our socks off to try and make some very special stories for this box set. Expect adventure, fun, scares… and some tears too.
