Final answer:
Actors during scenes perform a variety of actions directed by the script and the playwright's stage directions, and their performances are influenced by a multitude of factors including audience interaction, set design, and costumes. The use of special effects, sound, and lighting can also enhance the theatrical experience.
Step-by-step explanation:
During scenes, actors interpret their characters through a variety of methods, including the delivery of their lines and physical movements or actions that accentuate the play's meaning. Playwrights use stage directions to convey physical actions, which include anything from picking up a phone to significant movements that help to tell the story. The duality of the actor's performance, both the spoken words and the physical actions, contribute to an engaging narrative on stage. The choice of costumes and set design are also critical as they establish the time period, culture, and atmosphere of the play. Actors must adapt their performance techniques depending on whether they are acting before a live audience or a camera. When performing in front of a camera, the energy and scale of what is revealed are adjusted to fit the frame, with subtle nuances in expressions often taking precedence. Conversely, in a live theater setting, actors receive immediate feedback from the audience, which can influence their performance. In some productions, elements such as special effects, lighting, and sound are used to enhance the storytelling and involve the audience further.
