Hayley Atwell has said her new play The Pride resonates with the current debate on gay marriage, without getting on its soap box.
The Captain America actress stars with Harry Hadden-Paton, Al Weaver and Gavin and Stacey's Mat Horne in Alexi Kaye Campbell's play, which opens at London's Trafalgar studios on August 8.
The play explores a complex love triangle set simultaneously in the present and in 1958, against a background of changing attitudes towards homosexuality.
Hayley said: "Alexi was even saying today how much more current he feels it is, even from when he wrote it a few years ago, specifically because of gay marriage."
She added: "It tries not to be worthy or hit the point on the head too much, because then it would sound like a soap box lecture, which is absolutely not what the play is. It's full of heart and warmth, and there's comedy which undercuts the trickier stuff which is hard to digest initially."
Mat added: "It seems to be as we keep rehearsing it more and more salient and relevant, which is good for us."
The Pride is the third in the series Trafalgar Transformed, a season of politically themed plays directed by Jamie Lloyd at the theatre.
It follows his production of Macbeth, starring James McAvoy and Harold Pinter's The Hothouse starring John Simm, Simon Russell Beale.
The Pride runs until November 9 and tickets are available at www.thepridewestend.com.
