Based on the 2005 book, A Slight Trick of The Mind by Mitch Cullin.
In 1947, the long-retired Sherlock Holmes, aged 93, lives in a remote Sussex farmhouse with his housekeeper, Mrs. Munro, and her young son, Roger. Holmes reflects on his life while writing in his journals, tending to his bees, and dealing with the deterioration of his once incredible mind. The film, like the novel, uses flashbacks to reveal events of the past, when he was still at the height of his fame and mental ability at his Baker Street consulting rooms, and during a visit to Japan.
The casting stars Ian McKellen as the great detective Sherlock Holmes. Colin Starkey as John Watson, Laura Linney as Mrs Munro and Milo Parker as Roger Munro.
The film is directed by Bill Condon, produced by Iain Canning, Anne Carey and Emile Sherman. The film was written by Bill Condon and Jennifer Hatcher.
Mr Holmes is expected to be released with in 2015.
