Doctor Who: 5 More Potential Masters For Peter Capaldi's 12th Doctor

3. Andrew Scott

'He's the Napoleon of Crime' If he wasn't he is now. Since bursting onto screens into 2010 as Sherlock Holmes arch-nemesis James Moriarty, Andrew Scott has been thrust into the spotlight as, like his opposite Benedict Cumberbatch, a 'teenage dream', and a fantastic actor. Thirty seconds of one episode of Sherlock shows his ability to portray the sides of Moriarty - from talking in teasing, playful to tones to shouting and threatening in darker, more menacing octaves, Scott has the ability to portray a frantic yet infallible villain - and despite his apparent demise, will be remembered for a long, long time to fans of the show. The fact that he already can play one of Britain's most infamous villains would make him a prime candidate for the Master. In some ways, he is a younger version of John Simm's incarnation, drawing comparisons in both personality and appearance. But again, would he be willing, or more likely, would the BBC, be willing, to employ someone who is already well known as a villain? Much like Cumberbatch, he is perfect for the role, and would have no trouble filling it, but it is unlikely that so soon after playing one insane, frenetic, power-hungry apex of crime, he would play another. A cross-over with Doctor Who, however, in his original role as Moriarty, would not be out of the question.
