Back in September, The Guardian called Terry Coleman's biography of the late, great Sir Laurence Olivier "especially dispiriting"; according to Olivier's son, parts of it, at least, are just plain inaccurate. 68 year-old Tarquin Olivier objects to Coleman's claim that his famous father had an affair in the 1930s with actor Henry Ainley, despite confirmation from Olivier's ex-wife, Joan Plowright. The young Olivier is so angry that he's planning to give a 50-minute monologue at London's Chelsea Town Hall in January to tell his own version of events. "Most of it will be quite fun," promises Olivier, "But when it comes to the last part, it'll be a case of 'hold on to your belts'." And if Coleman decides to attend? Olivier says, "He'll need a drink."
