Her appearances on the boards may be few and far in between, but Annette Bening never strays too far from the theater. She earned an Oscar nomination for playing an English drama diva in 2004’s Being Julia. Last fall, she starred as Margo Channing in the Actors Fund benefit reading of All About Eve at the Eugene O’Neill Theatre.
