Movie Rumours
In late June 2009, just after the conclusion of Matt Smith's first series, an article emerged that reported that Depp had signed on for a Doctor Who movie, playing the role of The Doctor, for release in 2012 under then-recentely departed producer Russell T. Davies. The article quotes both Depp and Davies and subsequentely sparked a wealth of rumours, this was then exacerbated by reports of "falling ratings" during Smith's first series as The Doctor which, some reported, made it likely he would leave the role. The BBC have denied all rumours, dismissing them as "pure speculation".
