Breaking box office records on its first day of sales, the new production of Miss Saigon opened to tremendous acclaim at London's Prince Edward Theatre in May 2014. From the process of casting 40 actors from 18 different countries to the reinvention of the staging, including the famous helicopter scene, this film takes us on a journey through rehearsals right up to the star-studded opening night. Featuring interviews with legendary producer Cameron Mackintosh, authors Alain Boublil and Claude-Michel Schönberg and many of the award-winning cast and creative team, this is one of the most revealing documentaries ever made about how a major musical production comes to life.
