For those of you who might be worried about Steven Moffat taking over as lead writer and executive producer of Doctor Who, take comfort in the man's lifelong dedication to the show. In this video, fans get to see a bit more of departing Doctor David Tennant walking around the studios where Doctor Who has been filmed over the years and talking about the show.

Moffat, who takes over for previous lead writer and producer Russell T. Davies, remembers his father calling him excitedly to the television, saying Doctor Who was on. It wasn't the show's regular night, but Moffat rushed to the television anyway, only to find it was the kids show Blue Peter, which often promoted and previewed episodes of Doctor Who, and burst into tears.
