More random viewing: two obscure independent films from the BFI, Margaret Tait’s poetic Blue Black Permanent (1992) and Maurice Hatton’s gritty fake-umentary about the film business, Long Shot (1977); and three from Twilight Time – George Sluizer’s interesting Americanization of his existential thriller The Vanishing (1993), Terrence Young’s straightforward fact-based crime saga The Valachi Papers (1972), and D.W. Griffith’s monumental but deeply troubling Birth of a Nation (1915).
