Outpost Gallifrey is reporting today that Steven Moffat will be taking over as Head Writer and Executive Producer for Doctor Who with the fifth season in 2010. The BBC Press Office has issued an official release about the story. Moffat of course was written some of the best episodes of the new Who series, including The Emptry Child and The Doctor Dances from the first season, The Girl in the Fireplace from the second season, the fantastic Blink from the third series and the love letter to the fifth Doctor that was Time Crash. He is responsible for the upcoming fourth series two-parter Silence in the Library and Forest of the Dead. See Wikipedia’s entry on Steven Moffat for more about this multiple award-winning author.
RTD has quite literally been responsible for resurrecting the franchise but I am excited to hope that Mr. Moffat can not only keep Doctor Who going but constantly improving as well.
