The real-life husband of Sherlock co-creator Mark Gatiss, Ian Hallard often turns up in Gatiss' works, including ghost story series Crooked House and Agatha Christie adaptation Hallowe'en Party. In terms of Sherlock and Doctor Who, Hallard can be seen as the luckless lawyer to Jim Moriarty in The Reichenbach Fall who awkwardly has to admit to having nothing to defend the criminal with in court. In 2014, Hallard appeared in Mark Gatiss-penned Doctor Who episode Robot Of Sherwood as Robin Hood's lute-playing merry man Alan-a-Dale. Ian Hallard also played classic Who director Richard Martin in An Adventure In Space And Time, the 2013 docudrama about the sci-fi show's early years. It was written, of course, by Mark Gatiss.
