Bill Condon and Ian McKellen last worked together on the Oscar-winning Gods and Monsters. Their latest film posits a fascinating idea: what if Holmes was a real person? It finds the celebrated detective- played with raspy charm by McKellen – in his autumnal years, troubled by a few remaining mysteries and his deteriorating memory.

A beautifully mannered, gently moving and thoughtful film that offers a delightful final twist on the story of the world’s most famous detective.
