The first clip has been posted of Sir Ian McKellen playing Sherlock Holmes in the film Mr Holmes, based on Mitch Cullin‘s novel A Slight Trick of the Mind.

In a note on his Facebook feed, Sir Ian explained the set-up: “I am the intrepid detective Sherlock Holmes and here’s the twist: I’m 93 years old and working on my final case in consultation with a young confidant, Roger (played by Milo Parker.)

“Note: it’s just a clip—not the proper trailer that will soon be ready.”

Mr Holmes is released later this year.
