Can you imagine Kristen Stewart campaigning for an Oscar? Neither can we ...

But she's getting lots of buzz for her role in the upcoming film Still Alice -- including from Sony Pictures Classics' studio chief Michael Barker, who told The Hollywood Reporter KStew would make herself available during campaign season because "... she's fully supportive of this film in a major way." That is major!

Meanwhile, Stewart's got so many projects going ... she was promoting one of them at the Apple store in New York Tuesday night -- Camp X-Ray. Kristen plays a soldier assigned to Guantanamo Bay; her character befriends a man who's been imprisoned there for eight years. That film hits theaters October 17.
