A superb film all the way around except for the casting of Nancy Olson. Inexplicably, Olson won a supporting actress nomination from the academy that year, but I fail to see why. Her character gets on my nerves, especially making goo eyes at William Holden. But this is just a little quirk I have.
The film succeeds brilliantly mainly because of Swanson. It has an effecting score, great cinematography and great acting from the principle characters (Olson notwithstanding).
You will not be disappointed with this one!
I was slightly disappointed by the commentary track. The commentator, although knowledgeable in his subject, doesn't appreciate that most people watching the movie with commentary aren't seeing it for the first time. He will say things like, "And then Norma states a classic line," and will pause, and we wait to hear her say the classic line. Okay... but what's the point? This isn't the first time we've seen the movie, after all. I listen to commentaries to find out things I don't know, and in this respect the dvd is lacking.
Overall, though, every movie lover will want 'Sunset Boulevard' in his or her collection, and there is no reason to pass on this edition.
