Ian McKellen has unveiled a handsome teaser poster for his upcoming film Mr. Holmes, in which he stars as an aging Sherlock Holmes.

"Sorry to be a tease," the actor wrote his morning on Twitter, "but I hope you like it."

Based on Mitch Cullin's novel A Slight Trick of the Mind, the film opens in 1947 with a 94-year-old Holmes returning from Japan, where he was witness to the destruction caused by nuclear warfare. Living his a remote farmhouse with his housekeeper (Laura Linney) and her young son, the once-great detective comes to rely on the boy as he revisits the unsolved case that forced him into retirement.

McKellen, who revealed the first clip on Wednesday, reunites with Gods and Monsters director Bill Condon for Mr. Holmes. The film is expected to arrive sometime this summer.
