Ivo van Hove is renowned as one of the most innovative — and divisive — theatre directors working today. The Belgian's enthralling stage adaptations of classic works consistently subvert expectations. Now, van Hove's adaptation of the confronting novel A Little Life is coming to the Adelaide Festival.Also, a married lesbian couple with two children face divorce in Blessed Union, a new comedy at Belvoir, and Agatha Christie's The Mousetrap, the longest-running play on London's West End, is touring Australia. But is it a paragon of modern theatre or a tourist trap?
