One of the world’s top actresses, Meryl Streep, has called for the freeing of Oleg Sentsov, a Ukrainian filmmaker sentenced to 20 years in jail after being subjected to a sham trial in Russia.

The U.S. actress and renowned philanthropist was pictured alongside Ukrainian lawmaker Mustafa Nayyem with a “Free Sentsov” sign in a photograph taken during the PEN America Annual Literary Gala on April 25, at which Sentsov was honoured with a 2017 PEN/Barbey Freedom to Write award.
