What do you think makes Lewis such an enduring success? Everywhere I go, people talk about the production values of Lewis. Punters notice it, theyÃ¢â¬â¢re not stupid. I love the space in Oxford and the use of the city. It makes a huge difference, because, when it comes down to it, a lot of these cop shows are inevitably very similar. It makes such a difference to ours, having those locations and production values. How does the relationship between Hathaway and Lewis develop? We are still exploring the Hathaway relationship with Lewis. TheyÃ¢â¬â¢re developing that gradually as we did with Morse and Lewis. It still keeps me interested and we have a lot of fun doing it. I think the characters can develop more. There are some interesting guest appearances in the new series. Do you have any input on that? I donÃ¢â¬â¢t usually get involved with casting, but there are lots of wonderful people who still havenÃ¢â¬â¢t been in a Morse or Lewis film. When IÃ¢â¬â¢m watching television, IÃ¢â¬â¢ll make a note of particularly good actors who interest me. Any plans to get on the other side of the camera? No. ItÃ¢â¬â¢s long meetings and trying to juggle 28 departments. ItÃ¢â¬â¢s not me really; I like just focussing on the one thing. Did you give Laurence any advice when he became a father? He did well; I donÃ¢â¬â¢t think he was getting much sleep, but it didnÃ¢â¬â¢t affect him that much. He got advice from everyone, not just from me. Winston is a lovely little kid.
