KCTS (Seattle) had it on last night as their "viewers' choice" from the pledge drive, so I managed to record it. I caught about 5 minutes in between other stuff I was watching, and my initial impressions were that Valjean didn't have enough gravitas, and Marius looked about 12 years old ... but I'll reserve judgment until I've seen the whole thing. (BTW, for anyone else who gets the Seattle PBS, they're repeating it again next Saturday at 9 pm.)
My most recent Les Mis experience was a local theatre company's production. The performances were superb (probably the best Javier and Enjolras I've seen/heard, and that includes Broadway & West End), but they were on a smaller stage and it felt like they were bumping up against each other at times.
A movie in the works? That could be wonderful ... or awful if they let the cinematic elements overwhelm the music. But if they do the best of both worlds ... could be wow.
