For a long time there has been an inherent and intrinsic link between film and stage musicals but this tended to work one way, with stage shows being turned into movie musicals. However, there has been a recent trend of the opposite happening, with films being turned into hit stage musicals.
Emma Watson in 'Beauty and the Beast'. Emma Stone in 'La La Land'. *shudders* R-R-Russel Crowe in 'Les Miserables'. Hollywood seems to not care about whether or not their 'singers' in films can actually sing, but is it always a bad thing and why do they insist on doing it?
