Chewing the scenery is a theatrical term that refers to an actor's over-dramatic and exaggerated performance on stage. Synonyms for this term include hamming it up, overacting, scene-stealing, and grandstanding. These phrases are often used to describe performances that are too flashy, distracting, or over-the-top, drawing attention away from the main storyline. Other similar expressions include mugging for the camera, playing to the gallery, and histrionics. These terms are frequently used by critics to describe performances that are too showy, or by directors who want to coach their actors to tone down their performances and focus more on the story.
