I don't think of it as coming back - I'm trying to fight the idea that this is Morse revisited. It's the same character, but without John inevitably it's going to be a very different animal. A lot of the old Morse fans will tune in and I want to play down the expectations that it will be Morse, because it can't be. John was a particularly special actor - in my view he was the best TV actor we've ever had - so you want to aim high. But you can't expect it to be Morse. It's Lewis.
