James Pearson, sometimes credited as Jamie Pearson, joined the Doctor Who post-production staff as an editor in series 5, and continued on series 6 and 7.
Prior to his Doctor Who work, he was a longtime editor on MI-5. He also edited several episodes of the 2009 series of Law & Order: UK with Freema Agyeman and Bill Paterson; and about half of the first series of the Beth Willis/Piers Wenger-produced Ashes to Ashes. In the time between series 5 and series 6 of Doctor Who, he edited the Jonny Campbell-directed tele-movie, Eric and Ernie, for which he received his first BAFTA nomination.
