Academy Awards organizers have shaken up their show by doubling the best-picture category to 10 nominees in hopes of a broader range of films, mainstream movies mixing with the sober dramas that Oscar voters often favor.

The upside: If crowd-pleasers such as "Up" and "Star Trek" make the cut, it could give audiences more reason to watch the Oscars, whose ho-hum TV ratings often climb in years when blockbusters are in the running.

The downside: The Academy of Motion Picture Arts and Sciences could end up nominating 10 boring movies instead of the usual five, giving fans no new incentive to tune in to a show where rich and famous people spend a long evening patting the backs of other rich and famous people.

The show drew its biggest audience for the 1997 awards year, when "Titanic" swamped the box office with a record $1.8 billion haul worldwide and dominated the Oscars. On a general decline since, the ratings spiked for the 2003 Oscar when the final chapter in the "The Lord of the Rings" blockbusters swept the awards.

Here's a look at possible contenders for best picture and other top Oscar categories:

BEST PICTURE

By this time most years Oscar watchers generally have narrowed the best-picture prospects down to eight or nine films that have a shot for five nominations. Uncertain how academy members might vote for that extra five nominees, the pundits are flummoxed, with a couple of dozen titles getting attention.

Small and sober continue to dominate with Oscar forecasters, citing such dark tales as "The Hurt Locker," "An Education," "A Serious Man" and "Precious: Based on the Novel 'Push' by Sapphire" as contenders.

George Clooney's comedy "Up in the Air" has the best of both worlds, with strong critical support and a good start at the box office.

With great performances from Clooney, Vera Farmiga and Anna Kendrick, topical themes in its story of corporate downsizing and slick, smart direction by Jason Reitman ("Juno"), "Up in the Air" could emerge as an Oscar front-runner.

Both "Titanic" director James Cameron and "The Lord of the Rings" creator Peter Jackson are back.

Cameron has drawn raves for the visual innovations of his sci-fi epic "Avatar," though critics are less enamored of the story and its alien romance.

Jackson's drama "The Lovely Bones" has gotten a muted critical reception, though as a smaller story with narrower box-office prospects, it would not help the Oscar ratings much.

Along with "Avatar," "Up," "Star Trek" and "The Blind Side," other films showing up among the forecasts include Quentin Tarantino's "Inglourious Basterds," Meryl Streep's "Julie & Julia" and "It's Complicated."

The musical "Nine" — from director Rob Marshall, who made best-picture winner "Chicago" — has an all-star cast of Oscar winners and nominees and could break into the field.

Perennial awards favorite Clint Eastwood has prospects with his Nelson Mandela drama "Invictus."

Other films on the Oscar radar include "The Last Station," "A Single Man," "The Road," "Crazy Heart," "Bright Star," "The Messenger" and "The Young Victoria."

DIRECTOR

With just three films, "Thank You for Smoking," "Juno" and "Up in the Air," Jason Reitman has established himself as one of the brightest young talents in Hollywood.

The son of "Ghostbusters" director Ivan Reitman, he has had critics enthralled since "Up in the Air" debuted on the festival circuit late last summer.

Working from Walter Kirn's book, writer-director Reitman seized the novel's central idea of a traveling man disconnected from ground-level reality and created his own razor-sharp story around him.

With recession-era relevance in his tale of a man who fires people for a living — and the brilliant stroke of filming real people as they talk about losing their jobs — this could be Reitman's Oscar triumph.

Other possibilities:

Kathryn Bigelow, "The Hurt Locker"; James Cameron, "Avatar"; Jane Campion, "Bright Star"; Joel and Ethan Coen, "A Serious Man"; Lee Daniels, "Precious"; Clint Eastwood, "Invictus"; Rob Marshall, "Nine"; Lone Scherfig, "An Education"; Quentin Tarantino, "Inglourious Basterds."

BEST ACTOR

Two guys who already have supporting-actor Oscars make strong cases to take home the leading-man trophy, George Clooney as a frequent-flyer junkie in "Up in the Air" and Morgan Freeman as Nelson Mandela in "Invictus."

Daniel Day-Lewis, who has won two best-actor Oscars, is in the running again as a filmmaker in a creative funk in "Nine."

Then there's the Hollywood veteran of four decades, Jeff Bridges, nominated four times without winning. Bridges is terrific as an alcoholic country singer still belting out tunes at dive bars in "Crazy Heart."

Other possibilities:

Nicolas Cage, "Bad Lieutenant: Port of Call New Orleans"; Matt Damon, "The Informant!"; Colin Firth, "A Single Man"; Ben Foster, "The Messenger"; Viggo Mortensen, "The Road"; Jeremy Renner, "The Hurt Locker"; Michael Sheen, "The Damned United"; Michael Stuhlbarg, "A Serious Man."

BEST ACTRESS

Sandra Bullock, one of the most enduring box-office draws in modern Hollywood, has never been nominated. That might change with "The Blind Side," a football drama that has drawn Oscar chatter for Bullock's performance as a woman who opens her home to Michael Oher, a homeless teen now in his rookie season with the Baltimore Ravens.

Bullock's competition might include breakout performances from two twentysomething actresses.

After an apprenticeship in British TV and films, Carey Mulligan takes over the screen in "An Education," delivering a sparkling turn as an Oxford-bound 1960s teenager who puts her plans on the line when she takes up with an older man.

Gabourey Sidibe won the title role in "Precious" at an open casting call and makes her screen debut with a powerhouse performance as a Harlem teen overcoming a lifetime of abuse, neglect and illiteracy.

Other possibilities:

Emily Blunt, "The Young Victoria"; Abbie Cornish, "Bright Star"; Marion Cotillard, "Nine"; Helen Mirren, "The Last Station"; Meryl Streep, "Julie & Julia," "It's Complicated."

SUPPORTING ACTOR

Christoph Waltz was a respected TV and stage actor in Germany but virtually unknown elsewhere before his role as a gleefully savage Nazi in "Inglourious Basterds." With early supporting-actor honors from festivals and critics, Waltz is a strong contender.

Other possibilities:

Alec Baldwin, "It's Complicated"; Peter Capaldi, "In the Loop"; Matt Damon, "Invictus"; Woody Harrelson, "The Messenger"; Anthony Mackie, "The Hurt Locker"; Christian McKay, "Me and Orson Welles"; Alfred Molina, "An Education"; Peter Sarsgaard, "An Education"; Stanley Tucci, "The Lovely Bones."

SUPPORTING ACTRESS

More than a few awards watchers have stumbled over mentioning Mo'Nique and Oscar in the same breath this season. The actress previously known for lowbrow comedy turns in a remarkable performance as a despicable welfare mother in "Precious."

Other possibilities:

Penelope Cruz, "Nine"; Vera Farmiga, "Up in the Air"; Maggie Gyllenhaal, "Crazy Heart"; Anna Kendrick, "Up in the Air"; Melanie Laurent, "Inglourious Basterds"; Julianne Moore, "A Single Man"; Samantha Morton, "The Messenger"; Paula Patton, "Precious."
