Does this poster tell you all you need to know? It probably does, though I'll add that the screenings of The Big Smoke are encompassed by Mayor Johnson's Story of London festival. My views about that enterprise caused Boris's culture director Munira Mirza to tell me the other week that she "has a bone to pick with me." That's no reflection on The Big Smoke, though, which I hope to be able to go and see. Click on the poster to make it bigger.
