Because Matt Smith filmed this (BBC) movie during his break from playing the lead character in the BBC's hit television series "Doctor Who," the BBC gave Geoffrey Sax, this movie's director, strict instructions that Smith was never allowed to be shown nude. In a newspaper interview, Sax said, "They told me I must not show Doctor Who's bare bottom. They were quite firm about that, even though Matt was playing an entirely different character. They have invested a lot in him as the 11th Doctor and were due to make a second series with him, so they were obviously anxious to protect their property."
