Ben Wheatley's period drama A Field In England has been awarded the special jury prize at the Karlovy Vary International Film Festival.
The win, worth 15,000 US dollars, came days after the Civil War drama, starring Reece Shearsmith and Michael Smiley, launched on various platforms - in cinemas, on DVD and on TV - simultaneously in the UK on July 5.
Director Ben, who previously made Sightseers and Kill List, appeared in a special video thank you from the UK, while producer Andy Starke came on stage to receive the award in person, reported Screen Daily.
US filmmaker Oliver Stone promised to "keep exploring" in his emotional speech as he received his Crystal Globe for contribution to world cinema.
"There has always been a tension that haunted me way before Vietnam. My mother; my father; life itself, all my life. All these tensions will not allow me to let this award - or any this or any others - to stop me looking for the next undiscovered land," he said.
"I was born an explorer and when I cease exploring I will die. In that spirit I will say do not cease being out there young dreamers that exploration of yourselves. You will meet again and again deceit. But the next time out you will win this battle. Persist."
The director of films such as Wall Street and JFK added: "The world is always in need of regeneration and - filmmakers amongst others - can combine that somewhere out in this crowd. So if you can you, or several of you, can truly contribute to this world."
