Doctor Who: Rewind was a documentary co-produced by BBC America, BBC Worldwide and BBC Wales. It was essentially a recap of the story arc of series 5, with emphasis on the narrative points likely to recur in series 6. It debuted on BBCA immediately before their premiere of The Impossible Astronaut. It was a sequel of sorts to Doctor Who: The Ultimate Guide, a similar documentary made by many of the same BBCA crew.
