Wentworth Miller has come out as gay in a letter slamming Russia's stance towards homosexuals, it has been reported.
TMZ.com reported the star of hit show Prison Break outed himself in a letter declining an invitation to appear at the St Petersburg International Film Festival.
"Thank you for your kind invitation. As someone who has enjoyed visiting Russia in the past and can also claim a degree of Russian ancestry, it would make me happy to say yes. However, as a gay man, I must decline," Miller wrote, according to TMZ.
"I am deeply troubled by the current attitude toward and treatment of gay men and women by the Russian government."
"The situation is in no way acceptable, and I cannot in good conscience participate in a celebratory occasion hosted by a country where people like myself are being systematically denied their basic right to live and love openly."
"If circumstances improve, I'll be free to make a different choice."
Russia's new law outlaws the dissemination of homosexual "propaganda" to minors and has proved to be controversial, with calls for athletes to boycott February's Winter Games, set to be held in Russia.
Miller starred in four seasons of Prison Break, and wrote the script for recent release Stoker, which has had rave reveiws.
