Few film-makers can say that their work has made a change to the real world, but Morgan Spurlock had a stronger claim than most. His 2004 documentary Super Size Me, an exposé of how the fast food industry was fuelling America’s obesity epidemic, appeared to have direct repercussions for the world’s largest fast food chain, McDonald’s.
Shortly before the film came out in May that year, the company introduced its Go Active! menu, which included salad items; six weeks after its release, the company abolished its supersize portions entirely.
