After he completed "Red" (1994), the final film in his "Three Colors" trilogy,Krzysztof Kieslowski announced that he would retire. This was not a man weary of work. It was the retirement of a magician, a Prospero who was now content to lay aside his art--"to read and smoke." When he died two years later, he was only 56. Because he made most of his early work in Poland during the Cold War, and because his masterpiece "The Decalogue" consists of 10 one-hour films that do not fit easily on the multiplex conveyor belt, he has still not received the kind of recognition given those he deserves to be named with, like Bergman, Ozu, Fellini, Keaton and Bunuel. He is one of the filmmakers I would turn to for consolation if I learned I was dying, or to laugh with on finding I would live after all.
Is "multiplex conveyor belt" a set used in the film industry and the film negatives turn around it?
And does in this context the writer mean as the film was so long its film or negative do not turn easily along this device?
