"The coat was actually a couple of years old. What happened is that another chap did the pilot and he found that coat. When I took the project on, I inherited all those original costumes from the pilot. It was the only thing I kept. It was such a lovely coat - a classic. We had three of them because we obviously do stunts and need doubles. It is a lovely coat - really perfect for Benedict. He loved it, I loved it and everyone else seemed to."
