Career: Imrie's first professional jobs in showbusiness were in the chorus of various pantomimes. Her film and TV debuts came in 1974 in House of Whipcord and Upstairs, Downstairs. She continued to gain small roles in various productions, but her big break occurred when Victoria Wood offered her roles in As Seen on TV in 1985. Since then, she's continued to occasionally work with Wood and won a prestigious Olivier Award in 2006 for her role in Acorn Antiques: The Musical. Her other credits include Oranges Are Not the Only Fruit, Highlander, Gormenghast, Bridget Jones' Diary, Star Wars: Episode One, Doctor Zhivago, Frankenstein, Calendar Girls, Nanny McPhee and St Trinian's (and its sequel). On TV she has also appeared in Kingdom, After You've Gone, Cranford, and the acclaimed one-off drama The Road to Coronation Street.

Career: Gatiss eventually settled in London, where he hoped to earn a living as an actor but made ends meet writing Doctor Who books. He and friends Steve Pemberton, Reece Shearsmith and Jeremy Dyson formed The League of Gentlemen in 1995, which had successful stints on stage, radio, TV and film. Since then he's appeared in Bright Young Things, Marple, The Quatermass Experiment, Nighty Night and Jekyll. Gatiss was also script editor on the first Little Britain series, and has penned episodes of Randall and Hopkirk (Deceased) and Doctor Who (in which he's also appeared). He portrayed Malcolm MacLaren in the 2010 drama Worried About the Boy and co-created Sherlock with Steven Moffat.
