This time he means it: George Clooney will campaign for the best supporting actor Oscar for his role in "Syriana," reports The Envelope exclusively.

Initially, Clooney was positioned to campaign in the supporting race for his role as a bedraggled C.I.A. agent caught up in a U.S. conspiracy over Arab oil. It was clear to his Oscar campaigners and studio reps that the role was his best shot at a statue, since "Syriana" is a big-cast ensemble pic.
But recently Clooney pulled a shockeroo by overruling his peeps and proclaiming his candidacy for top gold.
Now Clooney's Oscar campaign strategy has flip-flopped.
The reason: A studio rep explains, "We've been listening carefully to members of the Screen Actors Guild, National Board of Review, the Hollywood Foreign Press Association and to film reviewers. Everyone decided, because this was best for the movie."
One of those reviewers was the Los Angeles Times' Kenneth Turan, who declared that director Stephen Gaghan "fiddles with the norms of studio storytelling in ways both nervy and unnerving, including treating all his stars like supporting players, the better to grapple with one of today's biggest stories, the ramifications of the fight to control the planet's dwindling supply of oil."
It was unlikely that Clooney, with limited screen time, could have squeezed into the crowded best actor category, which is dominated by more than a half-dozen strong front-runners. His chances are vastly improved in the supporting lineup, which seems wide open now.
Since Clooney also has a supporting role in "Good Night, and Good Luck," which he directed, many Oscarologists have been calling this "The Year of Clooney."
"Good Night" is a small pic though, and his role as a TV news chief is less showy emotionally. If blockbusters end up ruling the top races for best picture and director, voters will still have the option to hail Clooney for "Syriana."
It also helps that the role looks like classic Oscar bait, calling upon the handsome matinee star to uglify himself by donning a scruffy beard and packing on 30 pounds.
