Concept
In theatre, a thrust stage (also known as a platform stage or open stage) is one that extends into the audience on three sides and is connected to the backstage area by its upstage end. A thrust has the benefit of greater intimacy between performers and the audience than a proscenium, while retaining the utility of a backstage area. Entrances onto a thrust are most readily made from backstage, although some theatres provide for performers to enter through the audience using vomitory entrances. A theatre in the round, exposed on all sides to the audience, is without a backstage and relies entirely on entrances in the auditorium or from under the stage. As with an arena, the audience in a thrust stage theatre may view the stage from three or more sides. Because the audience can view the performance from a variety of perspectives, it is usual for the blocking, props and scenery to receive thorough consideration to ensure that no perspective is blocked from view. A high backed chair, for instance, when placed stage right, could create a blind spot in the stage left action. The thrust stage is the earliest stage type in western theatre, first appearing in Greek theatres, and its arrangement was continued by the pageant wagon. As pageant wagons evolved into Elizabethan theatre, many of that era's works, including those of Shakespeare, were performed on theatre with an open thrust stage, such as those of the Globe Theatre. The thrust stage was generally out of use for centuries, and was resurrected by Orson Welles when he staged Doctor Faustus for the Federal Theatre Project in 1937. The thrust apron extended over three rows of seats at Maxine Elliott's Theatre, extending 20 feet. "It was constructed especially for the production and was probably one of the first to break out of the procenium arch in a Broadway playhouse," wrote critic Richard France. Later resurrected by director Tyrone Guthrie and designer Tanya Moiseiwitsch, a thrust stage was used in 1953 by the Stratford Shakespeare Festival of Canada.
