Producers of the West End revival have released exclusive behind-the-scenes content from the rehearsal studio
In new footage released today, Miss Saigon producer Cameron Mackintosh says "there are 18 different countries represented" in the show, adding "I don't think that has ever happened with any show."
Director Laurence Connor tells the packed rehearsal room that casting for the show, which opens at the Prince Edward Theatre on 3 May, has taken 15 months and that the rehearsals will be "really, really tough".
The footage, which can be viewed below, also features Eva Noblezada, who plays Kim in the show, arriving in the UK for the very first time.
