Joss Stone And Stephen Fry In Scorsese Film
The Wolf Of Wall Street and Taxi Driver director is executive producer of the movie, entitled Tomorrow.
Directed by Martha Pinson, the film "explores the difficulty and loneliness soldiers encounter as they try to reintegrate back into society having served for their country".
Tomorrow is being billed as US director Scorsese's first foray into British feature film.
The film-maker said: "I'm honoured to join Martha in her directorial debut. Through her vision, the great cast and dedicated team, this story will resonate for years to come."
Stone's last big acting role was in 2010 as Anne of Cleves in The Tudors, the TV drama about Henry VIII.
QI host Fry stars in The Hobbit films and has been filming The Man Who Knew Infinity, alongside Toby Jones and Jeremy Irons. He also played the British prime minister in the latest series of 24.
Tomorrow will also feature Defiance actress Stephanie Leonidas, Game Of Thrones actor Paul Kaye and Philomena actress Sophie Kennedy-Clark.
Pinson, best known for her work as Scorsese's long-time script supervisor, said that the movie would tackle issues such as post-traumatic stress disorder, HIV and Aids.
"Tomorrow explores the difficulty of moving on from losses and injuries, to forge a life, to find sustaining work, and experience love," she said.
The film is being shot in London and Spain, and at Tedworth House in Wiltshire, which is a recovery centre for wounded serving and veteran members of the Armed Forces.
