Christopher Eccleston (The Ninth Doctor) was a guest on The Paul O'Grady Show earlier today - watch his interview in the player above. He doesn't chat about Doctor Who but he does give a very entertaining interview and dons a virtual reality head-set for some plank-walking fun.
Host Paul O'Grady had a cameo in the Series Four episode The Stolen Earth whilst you can also see Russell Tovey in the video, guest star in Voyage of the Damned (2007).
