I just had a brief comment. This is another great Russell Crowe movie, who just seems to get better (if possible) with each new flick. Crowe has to be one of the best actors currently working, in an era when we don't seem to have the same kind of great screen actors and actresses of past eras.
Rather, in recent years we seem to have artificially hyped and pumped up celluloid pseudo-greats with no real substance, and often, no real acting ability. In the midst of this it's refreshing to have at least one actor of Crowe's ability around.
Having said that, I must say I do like Meg Ryan, and she and Crowe make a great on-screen pair here, as she turns in a fine performance herself as the wife of the kidnapped engineer and dam builder.
I won't go much into the plot, as others here have already done so, except to say that the movie, once it gets going (and it gets off to a quick start) is an intense, powerful, interesting, and believeable drama from beginning to end.
All in all a fine movie. Big Steve says go see it and don't "Bogart" the popcorn.
