The crackdown on LGBT citizens has also prompted American actor Wentworth Miller to decline an invitation to the St. Petersburg International Film Festival, revealing that he's gay.
"As a gay man, I must decline," the 41-year-old former "Prison Break" star says in the letter.
"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," he adds.
"Wentworth's bold show of support sends a powerful message to LGBT Russians, who are facing extreme violence and persecution: you are not alone," GLAAD rep Wilson Cruz said in a statement. "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."
Miller wrote 2013's "Stoker," starring Mia Wasikowska, Matthew Goode and Nicole Kidman.
Here's the full text of Miller's letter:

Re: St. Petersburg International Film Festival / "Guest of Honor" Invitation
Dear Ms. Averbakh:
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.
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.
Perhaps, when and if circumstances improve, I'll be free to make a different choice.
