When the Gotham Awards are handed out in New York Wednesday, the winners won't necessarily be independently produced movies with a local flavor. That was the original mission of the event when it was established 16 years ago but times have changed, to the chagrin of some observers. This year's lineup of best feature contenders pits Sony's $40 million costume drama "Marie Antoinette" against indie label ThinkFilm's $1 million no-frills drama about a drug-addicted teacher, "Half Nelson." To some in the independent film community, this is a fair playing field where the best film wins. Gregg Goldstein reports.
