Rebellion: the Litvinenko Case (NC)

Andrei Nekrasov's documentary has edgy topicality – the fatal poisoning of Alexander Litvinenko in a London restaurant last November – but not much in the way of clarity or even cold, hard facts.

Before he died, the KGB agent explained to his friend Nekrasov his fears for the new Russia and his abhorrence of Putin's war with Chechnya, an outspokenness that made him an enemy of the Kremlin and may ultimately have been his undoing. But the film, instead of mounting a case to prove Litvinenko's murder, simply falls back on assertion, rumour and interviews with his widow. The sense of outrage is palpable, but some proper journalism is what's required.
