Russell Tovey: Was he tanned up, or was he tanned anyway?
Mark Gatiss: He’d just come back from Guadeloupe….
Russell: Death in Paradise, wasn’t it?
Mark: Yep. And it was impossible to ignore!
Sue Vertue: So we said “write it in!”
Russell: Oh, okay. So you actually wrote it in because of the tan?
Mark: And I tried to make it canonical, because he is all brown as a nut. Which is what Mike Stamford says about Watson…. But he looks great, doesn’t he?
