It was inevitable that Oliver Stone's trip to Havana to shoot 30 hours of interview with Fidel Castro would unleash a storm of controversy. Hawkish US commentators couldn't miss a chance to condemn Stone, and HBO, having bought the film, then decided not to show it. There's no doubt the director, who shares centre stage with Fidel himself, looks a little too pleased with himself for landing this coup, and as he develops a chummy camaraderie with his host, issues like Castro's human rights record and his laughable claim that Cuba is in some way democratic go without scrutiny.
