Look who made it to the cover of TV Guide.
Can you keep a secret? Probably not as well as Doctor Who executive producer Steven Moffat's two sons, Joshua, 13, and Louis, 11. These days, nearly every television producer, director, writer, actor and caterer is apprehensive about revealing details and plot points from unaired episodes of their shows. But Moffat is the master. He even gave one of the series' characters the catchphrase “No spoilers.” He purposely misleads the press. “I lied my arse off,” Moffat told 6,500 attendees at this year's San Diego Comic-Con regarding the content of an upcoming episode. He also runs a tight spaceship: Nondisclosure agreements are as ubiquitous as silver alien masks on the British science-fiction show's set.
