Farmor, I imagine the long hair being worn loose, particularly in the case of Fantine was to emphasise the great loss it would be when she sold it, bearing in mind she had lovely hair. I'm another who didn't particularly enjoy the film, ruined by the singing imo., particularly Russell Crowe's. Many years ago we were given tickets for the stage show but for some extraordinary reason the traffic was gridlocked on that particular evening due to a fatality, so we didn't make it. Shame because I've heard it's wonderful, a friend of mine has been to see it a few times.
Anyway, I'm enjoying this TV production, albeit very tragic. The pulling of the teeth scene was horrible, I had to look away.
