Perhaps that thing about Americans being hot for a British accent works in the other direction as well. The Society of London Theater handed out their prestigious Olivier Awards Sunday night and the top two prizes went to American works. Legally Blonde – The Musical was named Best New Musical and the MasterCard Best New Play award went to Bruce Norris’ Clybourne Park. (Do the producers and playwright get unlimited credit for a year?) Topping off the Yankee invasion, music theater legend Stephen Sondheim was awarded the Olivier Special Award and fêted with an all-star tribute lead by Angela Lansbury. Check out the Olivier Awards website for a full list of winners and pictures from the event.
