Nearing Christmas I couldn't think of a good festive question to ask you but I haven't asked you a question for many, many months so if it's okay I thought I'd ask you this one. When you worked on Doctor Who there were a number of stories like The Invisible Enemy and Underworld where you were required to act in front of a blue screen. CSO or 'colour-separation overlay' could be used pretty well to add or enhance the picture. My favourite use of this was in Warrior's Gate. That story looked amazing! My question is in today's industry do you find it easier to act with chroma key compared to back in the late 1970s when this was still a relatively new technique? Anyway thanks for answering this question and I hope it wasn't too dull.
By the way I hope you have a very Happy Christmas and an enjoyable New Year.
