The Eye of God, by Tim Blake Nelson was a great theatrical performance that was rehearsed, directed and performed by students. The "Black Box" theatre stage was very conductive to a personal, intimate feeling given from the players to the audience and even vice-versa. It was a modified thrust stage, only seated about fifty people, and was very, very dark in comparison to a large theatre setting. The stage space gave the audience the effect of being right in the middle of the action, influencing the impact of the production by making the audience lose track of who they are and putting them inside the play itself.
In the "Black Box" theatre space the director can have many different arrangements to his/her theatre. That flexibility means the designers can create a proscenium, an arena, a thrust, multifocus, or any combination of these. For instance, the designer might want the stage at the front and the audience to be looking through a "4th" wall. In this form of arrangement it would be called a proscenium. A thrust stage has an equal amount of audience on the left, right and center of the stage, letting more people be closer to the stage. A multifocus stage has different areas for the actors to perform. The director could have the bulk of the action to be on the center stage, but wanted a scene or two to be behind the audience; that would be the purpose of having a multifocus theatre. The arrangement in Eye Of God was a modified thrust meaning that it was part proscenium; part thrust and had a very small amount of multifocus theatre in it. .
The stage space gave the audience the effect of being right in the middle of the action, influencing the impact of the production by making the audience lose track of who they are and putting them inside the play itself.
Let me clarify what I meant by saying that the stage space gave the audience the effect of being right in the middle of the action.
