I went to see Sunset Blvd today at the Signature Theatre in Arlington, VA. It was very enjoyable. Florence Lacey plays Norma, DB Bonds is Joe and Susan Derry plays Betty Schaefer.
The stage is surrounded by the audience on three sides. The designers were very creative in the use of limited space. The staircase is on the left side of the stage as opposed to the center. The orchestra is above and behind the stage in a very small space. The car is on a track at the back of the stage but also runs on electricity according to the tour "guides" ( I went on a "backlot tour" after the show. Two of the actors were the guides--the aforementioned Susan Derry and another actor who had one of the smaller roles.
