The London production of Les Misérables, the world's longest-running musical, has just kicked off its amazing 40th year and is still packing theaters with sold-out crowds.

Sir Cameron Mackintosh has put together a reimagined arena version of the show, which has received rave reviews across the UK and major cities in Europe. 

The undisputed leading lady of Australian musical theatre, Marina Prior, will star as Madame Thenardier.

Ms Prior told Sofie Formica on 4BC Afternoons, "it is such a special show, any opportunity to be doing Les Misérables again... I am just so honoured to be a part of it."
