Every so often there comes a man who is able to see the universe in a totally new way, whose vision upsets the very foundations of the world as we know it. Perhaps the greatest scientific genius of the 20th century, Albert Einstein, 730 Monday. For 13 years, nuclear tests in Kazakhstan were conducted above ground. Years later, the echoes of those explosions can still be heard. This week on the cutting edge, previously secret footage shot by the Soviet army, and an interview with Andrei Sakharov only hours before he died. Testing Ground, a Soviet nuclear secret, 830 Tuesday on the cutting edge. On Wednesday night, a treat for all cinema buffs, at 930, the life and times of Don Luis Buñuel. A film which explores his entire career and sees him emerge as a master of contradiction. He was a surrealist, a revolutionary, completely when he was young and also when he was old. At the same time, he led a very bourgeois life. Then at 1030, the last film he ever made, that obscure object of desire, a surreal vision of an obsessive liaison. Embrace le bas de ma robe et mon pied. Wicked and witty, a double dose of Don Luis Buñuel, Wednesday night on SBS. Thank you for watching!
