Benjamin Cook is a writer and interviewer for Doctor Who Magazine. Between 2007 and 2008, Cook collaborated with Russell T Davies on an extensive correspondence that formed the basis of the 2008 book release Doctor Who: The Writer's Tale, which was issued in an expanded second edition subtitled The Final Chapter in 2010.
Cook's friendship with Davies, chronicled in the book, has had a lasting impact on the series itself, as The Final Chapter acknowledges that Cook was responsible for convincing Davies to abandon plans for a cliffhanger ending to Journey's End.
Cook worked on many of the DWM episode previews. He previewed most episodes of Series 8 along with David Bryher, and previewed the opening Series 9 two-parter The Magician's Apprentice / The Witch's Familiar in DWM 491, while Jason Arnopp previewed Under the Lake / Before the Flood.
