It’s A Sin creator Russell T Davies has said he believes gay roles should be played by gay actors.The writer and showrunner, who also worked on Queer As Folk and A Very English Scandal, said “it’s about authenticity” when discussing the ongoing debate.Ahead of his upcoming Channel 4 series It’s A Sin, following a group of young gay men who move to London during the AIDS epidemic in the 1980s, Davies spoke of his decision to cast gay actors.The show is set to star Years & Years‘ Olly Alexander, as well as Neil Patrick Harris and Stephen Fry.“I’m not being woke about this… but I feel strongly that if I cast someone in a story, I am casting them to act as a lover, or an enemy, or someone on drugs or a criminal or a saint… they are not there to.
