Wentworth Miller, the actor best known for starring in the US television series Prison Break, has come out publicly as a gay man.
Miller, also a successful screenwriter, was invited to be a guest of honor at the St. Petersburg International Film Festival.
He turned down the invitation and cited Russia's anti-gay laws as the reason.
'As a gay man, I must decline,' he wrote after thanking the festival for the invitation.
Miller said he has enjoyed visiting Russia in the past and also claims a degree of Russian ancestry.
