Acclaimed TV writer Russell T Davies has said that straight actors should not play gay characters.

Best known for his work on Queer As Folk and Doctor Who, Davies is due to return to the screen with the much anticipated new Channel 4 drama It’s A Sin, which explores the HIV crisis in London in the 1980s.

Years and Years singer Olly Alexander, who is openly gay, stars in the lead role as a promiscuous aspiring actor.

There has been much debate in recent years over whether straight actors should portray gay characters.

Speaking to the Radio Times, Davies compared a straight actor playing a gay character to black face.

He said: “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 ‘act gay’ because ‘acting gay’ is a bunch of codes for a performance.

“It’s about authenticity, the taste of 2020.

“You wouldn’t cast someone able-bodied and put them in a wheelchair, you wouldn’t black someone up. Authenticity is leading us to joyous places.”

High-profile examples of straight performers playing LGBTQ+ characters include Rami Malek‘s Oscar-winning portrayal of Freddie Mercury in Bohemian Rhapsody, and Taron Egerton‘s Golden Globe-winning turn as Sir Elton John in Rocketman.

In December, British TV presenter and actor James Corden was accused of “gay face” following his role in Netflix musical comedy The Prom.

In September, Netflix adapted the 1968 play The Boys In The Band, the story of a group of gay men who gather for a birthday party.

While both gay and straight actors were auditioned, the nine characters all ended up being played by gay men.

Director Joe Mantello told Sky News the casting was not intentional, but rather a “very fortunate series of events”.

He continued: “That being said, I think having an out gay cast really did inform the work and it took on a particular kind of tone because of that, which is not to say that’s the only way to approach this material. But for this particular group, it did something that I think is very, very special. There’s a chemistry that they have.”
