48 years old (Born on April 18, 1971)
Scottish actor; He is famous from Doctor Who, Hamlet.David (and his Doctor Who co-star Catherine Tate) were chief investors in their 2011 stage production of 'Much Ad About Nothing'. The production took u00a33 million in ticket sales before press night. On August 31st 2007, he turned on the illumination lights for Blackpool. Attended Paisley Grammar. In 2009, he was cast in the film 'Burke and Hare,' playing William Hare, which was filmed in early 2010. However NBC forced him to drop out of the role, as he had recently filmed a TV pilot for a show called 'Rex Is Not Your Lawyer' and he was still under contract to them. NBC originally made the Rex pilot as a potential Fall 2010 show, but when the Today Show crisis happened, they considered putting it into production as a mid-season replacement, which meant that David would be needed to film earlier. Ironically NBC never picked up Rex at all, meaning David lost the Burke and Hare role needlessly. Andy Serkis went on to play the role of Hare.
In January 2012, David recorded a voice-over movie role (in The Pirates), an audio book, a radio play (Waiting for the Boatman), filmed a TV presenting job (Prefaces to Shakespeare), did press interviews, hosted the BBC Audio Awards, and attended several charity events.
