Is it all singing or do they speak in it? Never seen the stage show and really dont know much about it but just watched the clips on Film 2013 and all the clips were singing clips. Not sure if I could sit through two and a half hours of non stop singing.
It's a sung-through musical - no dialogue at all onstage. In the movie there are a couple of ad-libs from Sacha Baron Cohen and a few lines of dialogue but nothing else. There would have been a huge outcry if they hadn't done it sung through.
