It’s not enough that we already have three Sherlock Holmes TV series (that’s right, three- Sherlock, Elementary, and an upcoming Russian series) and Guy Ritchie’s Sherlock Holmes films. As a society, we’re not running anywhere near our full capacity for producing Holmes-related media. There must be no stopping until we have entire world economies based around adapting Sir Arthur Conan Doyle‘s works. Every TV channel, every theater and every bookstore will overflow with deerstalker caps, pipes, and magnifying glasses. Ian McKellen has the right idea. The actor has just signed on for A Slight Trick of the Mind, as an older, retired Holmes who investigates an unsolved case without the aid of Watson and with his famous intellect drifting away with age. Technically, it’s not actually one of Conan Doyle’s stories- it’s based off a novel originally released in 2005 by author Mitch Cullen, but McKellen fits so perfectly for this role that it’s more or less impossible to complain.
