American Idiot is doing great business over at Berkeley Rep. The show has already become the theatre company’s top-grossing show, breaking advance sale records before the show even opened. Now, following a three week extension announced at the start of the month, the show will play an additional two weeks, closing on November 15th. Quite a good run for a show that received mostly mixed reviews and mixed reactions from audiences – although some have certainly raved about it, no doubt fueling the word-of-mouth machine that is propelling the show to its immense commercial success.
