When is a bastard prompt used?

A bastard prompt is utilized specifically when the prompt corner is required to be stage right, facilitating a certain arrangement for the performance. This terminology arises from the need for stage managers or actors to have the script or cues visible from the designated right side of the stage, ensuring clarity and efficiency during a production.

When the prompt corner is placed stage right, it encourages the flow of communication and coordination between performers and the stage crew. This situation is essential in various theatrical contexts, where actors may need immediate access to their cues or direction from that particular side of the stage. The other choices do not accurately capture the definition or application of a bastard prompt, which is made specifically for performance logistics rather than location or context.
