The Road to Guantanamo, the film about three Muslims from the Midlands held at by the US at the detention centre, is to be released in cinemas in America.
Independent US distributor Roadside Attractions plans to premiere Michael Winterbottom's film at the Tribeca Film Festival and release it early in the summer, according to Variety.
"We think this film is a visceral punch to the gut that will leave everyone thinking about Guantanamo in a new way," co-president Howard Cohen said.
The controversial film follows the true story of Asif Iqbal, Ruhel Ahmed and Shafiq Rasul, the socalled Tipton Three, who set off from their Midlands home town for Pakistan in September 2001.
Through a series of interviews with the men, dramatised scenes and news footage, it shows how they ended up in Afghanistan under fire from American bombers, hiding with Taliban fighters, being captured by the Northern Alliance and handed over to the US and kept in nightmarish conditions. They were released in 2004 without charge.
The film, which cost £1.4 million to make, won a Silver Bear award in Berlin this year.
