An actor in London took it upon himself to take a stand against homophobia, as he chastised an audience member for making a homophobic comment during the embrace of two male characters.

The man in question was among audience members at The American Plan on Wednesday, and loudly tutted, before saying: “Makes me sick”, commenting on the embrace between the two male characters, Nick and Gil, reports the Evening Standard.

Mark Edel-Hunt, who plays the character Gil, responded to the abuse by returning to the stage at the end of the curtain call with a sign depicting the Stonewall slogan: “Some people are gay. Get over it!”

The play tells the story of New York during a 1960s summer, when the daughter of a wealthy German-Jewish refugee falls in love with a stranger at a holiday camp in the Catskill Mountains.

In an unexpected twist in the second half of the play, Nick, who appears to be straight, reveals that he has had an affair with Gil.

The show debuted in New York in 1990, and has been revived by the Theatre Royal, Bath. It plays at the St James Theatre until 10 August.
