Leslie Unger, a spokeswoman for the Academy of Motion Picture Arts and Sciences, says none of the superstar presenters will be announced before the February 22 telecast.
Awards shows, including the Academy Awards, typically tout celebrity presenters to generate interest. But Oscar producers Laurence Mark and Bill Condon are breaking tradition. They're hoping to lure TV viewers by keeping the star power a secret until showtime.
Unger said Wednesday: "There will be fantastic movie stars that appeal to a whole range of movie lovers and fans of our show. We're just not going to tell you who they all are."
The Oscars will air live from the Kodak Theatre.
