Only God Forgives, the latest film from Danish director Nicolas Winding Refn, opens this week in the US as it continues its release around the world.
Hollywood star Ryan Gosling plays Julian, who runs a boxing club in Bangkok that is a front for a drugs operation. When his sleazy, violent brother is killed, his vindictive mother, played by Kristin Scott Thomas, flies into town to seek revenge.
The film is extremely violent: eyes are gouged, limbs pierced and body parts sliced off. Does violence on screen alter viewers’ attitudes to violence in the real world?
Tom Brook puts the question to Ryan Gosling and Nicolas Winding Refn, and gets two very different answers.
