Wentworth Miller's 'Prison Break' co-stars were quick to express their support for the actor's decision to finally come out of his closet and admit that he is gay.

Miller, 41, made the revelation through a letter addressed to the St. Petersburg International Film Festival's director, Maria Averbacj. He was originally invited to be the film festival's guest of honor but due to Russia's newly adopted anti-gay laws, the actor refused to go as a mark of his condemnation to such laws.

He wrote, "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."

The Britain-born actor and producer who also had cameo roles in Mariah Carey's music videos further detailed his denunciation of the country's unfair treatment of the LGBT community: "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."

Last July, Russia's president Vladimir Putin officially signed a law which bans gay couples from adopting Russian children. Prior to this law, a bill was similarly passed in 2012 forbidding gay pride events in Moscow.

Miller, who played the imprisoned structural engineer Michael Scofield in 'Prison Break' was immediately supported by his co-stars. Amaury Nolasco tweeted:

"I applaud my boy, Wentworth Miller's courageousness. I'm proud of you brother, for standing up for what you believe in. Enough is enough!"

The letter was likewise posted on the website of GLAAD, an online group which monitors LGBT media materials. The group's spokesman Wilson Cruz couldn't be prouder of the actor's decision: "Wentworth's bold show of support sends a powerful message to LGBT Russians, who are facing extreme violence and persecution: you are not alone. As people from across the globe continue to speak out against Russia's horrific law, more celebrities and corporations should follow his courageous lead in openly condemning Russia's anti-LGBT law."

The response of the film festival's governing body is yet to be heard.
