Wonderful adaptation of the musical. I saw the London version of the stage production and the movie is a good representation of the stage. For the most part, the original cast was used. Yes, they were 10 years older, but they certainly knew the parts. This movie didn't do well, and that's a shame, it is an excellent movie. See it - it is worth your time. Maybe it would have done better if it had cast Meryl Streep and other well known actors that can't really sing. I doubt that would have worked, the songs in Rent are much more difficult than the Abba songs in Mamma Mia.
