TELLURIDE, Colo.

--Two years ago, a prominent Oscar voter left the Telluride Film Festival's world premiere screening of "The King's Speech" and said with certainty that the film would be shortlisted for best picture. At the festival last weekend, that same voter issued a new prediction: Ben Affleck's "Argo" will be among the finalists for the top Academy Award.

The Telluride festival, which concluded its 39th annual installment on Monday, prides itself on eccentric programming (among the offerings was the nearly three-hour Russian film "Stalker" from 1979) and against-the-grain tributes (the 2012 actor award went to Denmark's Mads Mikkelsen). But in recent years the Labor Day weekend gathering has become something of a herald of awards season success.

In addition to booking the best picture winner "King's Speech," Telluride programmers over the last few festivals have scheduled the world or North American premieres of "Slumdog Millionaire," "The Artist," "The Descendants," "Black Swan" and "A Separation," all of which either won or were nominated for prominent Academy Awards.

It's a record the festival feels conflicted about, as Telluride officials would rather their lineup be more focused on surprises than trophies.

"I worry about the time when we don't have 25 Oscar nominations for films playing at the festival," said Gary Meyer, who with Tom Luddy and Julie Huntsinger directs the festival. "It's not our purpose in life."

In this year's schedule, the programmers partially may have achieved their desire. Though "Argo," a story about the 1980 rescue of State Department employees hiding in Iran during the hostage crisis, will leave the mountain resort town with tremendous momentum heading into its Oct. 12 release, the festival did not clarify a clouded awards picture.

In large measure, that's a reflection of the movies Telluride couldn't play, mostly because they weren't finished. Meyer said the festival would have loved to consider Ang Lee's "Life of Pi" and Steven Spielberg's "Lincoln," but neither film was completed, the same as with Sacha Gervasi's "Hitchcock," which hasn't yet been added to the 2012 release calendar.

Concerned that the makers of Paul Thomas Anderson's "The Master" had held too many sneak previews around the country, Telluride programmers declined to invite that film, and they also refused to book the sex surrogate story "The Sessions," which had played in January's Sundance Film Festival.
