I came across this by accident, broadcast over 3 nights on TV - I recorded it, and watched the whole thing without being able to leave the sofa. It is the best movie I've ever seen.
4½ hours long, subtitled black-and-white Victor Hugo epic doesn't sound appealing, or only to 'art house' fans, but not so ... if you ever get a chance to see it, do!
The acting is tremendous, as is the cinematography. Certain visual moments are forever imprinted on my mind, such as the moment when a helping hand comes out of nowhere to help the collapsed Cosette, or the moment when a nun, sworn to always tell the truth, lies to protect the protagonist, Jean Valjean.
It is a superb retelling, and remains the best version of this classic novel. What makes it even more poignant is how themes in the movie were reflected in the real lives of the actors. Harry Baur, who plays the lead - a man falsely imprisoned and whom is relentless pursued through the film - lost his life a few years later at the hand of the Gestapo for being suspected of aiding the resistance, and Gaby Triquet (the young Cosette) was shamed and blacklisted for having an affair with a German soldier and never worked again.
I've seen a few 1930s features, and while enjoying them, would not expect others to sit through them. Not this! It is everything a good movie is about - superbly crafted, mesmerising to watch, and leaves you seeing the world slightly differently afterwards. I've never seen better.
