Sir Ian McKellen will be the latest actor to take on the role of Sherlock Holmes, as he is set to take to the big screen to play an aged version of the legendary detective.

The Lord of the Rings star will play the role of Sherlock in a film adaptation of Mitch Cullin’s Novel, and will again work with his Gods and Monsters filmmaker Bill Condon.,

In the new film, Sir Ian will play the character as a long-retired consulting detective, who still laments over an unsolved case from fifty years prior. In the book, A Slight Trick of the Mind, Holmes begins losing his memory, and without Dr Watson, can only remember parts of what has happened.

It is expected to start shooting in April 2014.

“A perfect match for this clever and intriguing project”, was how executive producer Aviv Giladi described the pairing of Sir Ian and Twilight: Breaking Dawn director Condon.

The two worked togther in 1998 on Gods and Monster, which earned Sir Ian a nomination for best actor Oscar, and Condon an Oscar for his screenplay.

The famed hero has been played recently by Robert Downey Jr, with Jude Law as Dr Watson, and by Benedict Cumberbatch in a BBC series, alongside Martin Freeman, and Jonny Lee Miller took on the role in US television series Elementary.

Sir Ian McKellen recently became the latest celebrity to show his support for LGBT Russians who are facing increasing persecution from the state.

The actor and gay rights campaigner was photographed with a pro-Russian LGBT rights flyer by the blogger Michael Petrelis. The photograph was taken following a performance of Harold Pinter’s No Man’s Land on New York’s Broadway that Sir Ian is currently appearing in with the Star Trek star Sir Patrick Stewart.
