Well, the Oscars are about money (and politics, and prestige), beginning with the financial numbers for television, where it's known alternatively as the Women's Super Bowl (and the Gay Super Bowl). The numbers aren't quite up there with the SB, but they are big enough. The Oscars are also supposed to help at the box office, but there's some disagreement about this.
Traditionally, nominees are helped by their studios – lobbying efforts, special events held for Academy members, and so forth. This can hurt nominees from films from the same studio, because then the institutional effort is divided (as happened this year, when Rob Marshall and Martin Scorsese received nominations for movies from the same source).
Lobbying efforts that are too naked can backfire. A notorious example until recently was Berry Gordy's aggressive efforts on behalf of Diana Ross for "Lady Sings the Blues" -- people were turned off, and she lost when she might very well have won. The wins for "The Pianist" have been interpreted as part of a backlash against Miramax (too much to go into here and too far from our topic). And "The Pianist" was in its way a well-connected movie – Polanski has lots of pals from way back when.
However, the Academy has shown an inclination to reward movies that reflect – I wouldn't say art so much as respectability. This isn't necessarily a bad thing. It gives Hollywood a chance to show the world that Money Isn't Everything, and it gives exposure to good films that might not reach a larger audience – "The Pianist" has been playing at multiplexes it would never have got to without all those nominations. (You could also argue, though, that it's a way of relieving bad consciences – they can produce dreck for most of the year, release a few Prestige Productions in time for the Oscars, and congratulate themselves for their efforts.)
I think you're right, Calliope. Kidman was probably exhausted at having to get up every fifteen minutes or so for yet another ovation.
You may be right, GWTW. Kidman will have to give out the Best Actor award next year, so she'll have to keep her fingers crossed , I guess.
Assuming, for the moment, my role as board cop, I'd suggest to people with inquiries of the "Has anyone seen Such-and-Such?" type to please begin a new topic. There's plenty of room for new threads, and could lead to long and fruitful discussions. Thanks!
