Robert Innes Hopkins, designer of this production of Macbeth, uses the model box to explain the set design which we see in these extracts.
For the RSC's 2004 Tragedies season, there was an overall design for the shape of the RST stage which had a straight front edge. Each of the three productions had to fit its design to this overall shape.
For Macbeth, this stage shape with its square feel, contributed to the blunt masculine strength of the play. The designer of any production needs to consider practicalities like exits and entrances, how the action will work and more abstract issues such as the use of texture or colour to create atmosphere. In this production, Robert Innes Hopkins used a dark-grey tone to create a feeling of harshness.
Most designers create a model box for the production - a 1:25 scale model which helps to inform the workshop team as they manufacture the set. The model box is also an essential tool enabling the designer and director to communicate ideas easily so the design will support and enhance the action.
