The term 'Actors Undertones' refers to the subtle nuances of an actor's performance that are often overlooked. These undertones can be seen in the way an actor speaks, moves, and interacts with other characters. Asides, which is a six-letter word, are lines of dialogue that are spoken directly to the audience, usually for comedic effect. Asides are used to provide insight into a character's thoughts or feelings, and can be used to add depth to a performance.
