Les Miserables is the world's best-loved musical. It has been seen by 57 million people and in 2010 celebrated its 25th anniversary with its two largest ever productions at London's O2 Arena. Matt Lucas, a lifelong fan of 'Les Mis', was invited to fulfil his dream of performing in these shows alongside more than 300 stalwarts from previous productions. This documentary tells the story of a musical that many thought would fail, but which became a worldwide phenomenon with unforgettable songs like I Dreamed A Dream. We follow Matt as he prepares for the performance of a lifetime, we hear from those involved with the show's creation, including Cameron Mackintosh and Michael Ball, and of course we enjoy wonderful moments from the show itself.
