LONDON — “Game of Thrones” actor Iain Glen has joined the cast of psychological thriller “Beautiful Devils,” which started filming in London last week. The movie is a modern adaptation of William Shakespeare’s “Othello,” set in the world of the contemporary music business.

Glen, whose credits include the role of Lady Mary’s beau Sir Richard Carlisle in “Downton Abbey,” plays alongside a raft of up-and-coming talent, including Osy Ikhile, who appears in the upcoming “Mission: Impossible — Rogue Nation,” Elliot James Langridge (“Northern Soul”), Rachel Hurd-Wood (“Home Fires”), and Danny Horn (“Emmerdale”). Others appearing include comedian Rufus Hound, making his feature film debut, and established thesp Steve Waddington, whose credits include “The Imitation Game.”

“Beautiful Devils” is directed by James Marquand (“One Night in Istanbul,” “The Boy with the Thorn in His Side”), and is produced by Ascension Productions’ Craig Tuohy, alongside Carnaby Intl.’s Andrew Loveday, Mike Loveday and Terry Loveday. Carnaby has secured worldwide sales rights to the film.

The pic sees up-and-coming musician Oz (Ikhile) abandon his friend, confidant and musical side-kick Ivan (Langridge), in favor of his lover Darcy (Hurd-Wood) and her friend, the talented Casper (Horn). Ivan remains close to Oz as he rises to stardom, all the while secretly setting out to ruin his former friend. Ivan ropes in the services of the malleable Rigo, the producer’s son who holds a grudge against Oz because of his unrequited love for Darcy. Together they set about destroying the new group and their lovers through lies, treachery and murder. Channeling the themes of ambition, greed and the pressure of social media culture, the film, like the original play, ends in bloody tragedy.

“Beautiful Devils” is filming in the U.K. around the urban areas of East London, giving it a dark gritty feel to match the tone of the tragic story. Filming commenced on June 1 and is scheduled to wrap on July 5, and will receive its theatrical release in the spring of 2016.
