Cameron Mackintosh’s newly conceived touring production of “Les Miserables,” the world’s longest-running tuner, will play a three-week sitdown at London’s Barbican Theater Sept. 14-Oct. 2, ahead of a three-year tour of the U.S. being lined up for 2011.

Production, which opened in Cardiff in December, is helmed by Laurence Connor and James Powell, featuring new sets by Matt Kinley and lighting by Paule Constable. Tour has broken box office records in Manchester, Norwich and Birmingham.

London run coincides with the 25th anni of the original Trevor Nunn-helmed production, which continues at the Queens Theater. It will be the first time that two productions of the same musical are playing simultaneously in the same city.
