I recently visited Mexico at the invitation of Esteban Volkov, Trotsky's grandson, to participate in the filming of a documentary about the life and death of the great Russian revolutionary. The documentary, by the Argentine-Mexican director, Adolfo Videla, was filmed in the house in Coyoacan where Leon Trotsky lived for the last few years of his life, together with his faithful companion and comrade, Natalia Sedova. The documentary draws on rich archive material and includes valuable contributions by people like the French Trotskist historian Pierre Broue. It is due to be shown on Mexican television in the autumn.
