New faces for Holmes regulars

Brydon will play Scotland Yard man and frequent collaborator of Holmes, Inspector Lestrade, while Macdonald will play Holmes’ stalwart and long suffering housekeeper, Mrs Hudson. Hall, meanwhile, will play Dr. Grace Hart, described as the first female doctor to practice in London. They join Ferrell as Conan Doyle's master sleuth, while Reilly plays his loyal companion and confidant, Watson. Lauren Lapkis will also be playing a role, called 'Millie', though what purpose she will serve has yet to be disclosed by the film's production team.

Not the first Holmes comedy

With a character as popular and long lasting as Holmes, many interpretations exist, including comedic ones. These vary from simply being parodies, to all new stories with comic twists or sequels. Some of the most well known include: 'The Adventure of Sherlock Holmes' Smarter Brother' (1975), starring Gene Wilder and his 'Young Frankenstein' co-stars Marty Feldman and Madeline Kahn; 'The Strange Case of the End of Civilization as We Know It' (1977), starring John Cleese as a descendant of Holmes; a comedic reinterpretation of 'The Hound of the Baskervilles' (1978) starring Peter Cook and Dudley Moore, and 'Without A Clue' (1988), starring Michael Caine and Ben Kingsley as Holmes and Watson respectively, albeit now with the roles reversed.
