Prison Break actor Wentworth Miller has come out as gay in an open letter protesting Russia's anti-gay laws.
The 41-year-old was invited to appear at the Petersburg Film Festival but declined due to the country's recent legislation.
"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," Wentworth wrote in the letter to festival director Maria Averbakh.
"However, as a gay man, I must decline.
"I am deeply troubled by the current attitude toward and treatment of gay men and women by the Russian government," he continued in the letter, posted on GLAAD's website.
"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."
GLAAD spokesman Wilson Cruz praised Miller's actions.
"Wentworth's bold show of support sends a powerful message to LGBT Russians: you are not alone," Cruz said.
"As people from across the globe continue to speak out against this horrific law, more celebrities and corporations should follow his courageous lead in openly condemning Russia's anti-LGBT law."
Russia's parliament banned the spread of gay ''propaganda'' among minors in a law passed in June, which includes imposing fines on those holding gay pride rallies, has attracted international condemnation.
Miller, who played incarcerated structural engineer Michael Scofield in Fox's Prison Break from 2005 to 2009, has recently turned his hand at screenwriting, penning the script for this year's dark thriller Stoker, starring Nicole Kidman.
Miller's letter comes after Bravo channel host and executive producer Andy Cohen told E! News last week that he would not be co-hosting Donald Trump's Miss Universe pageant this year in Moscow because he ''didn't feel right as a gay man stepping foot into Russia.'
