The term "actor's lines" is commonly used in theater and film to refer to the dialogue that a performer must deliver during a scene. However, there are a number of synonyms that can be used to describe this aspect of an actor's work. These might include phrases such as "scripted dialogue," "dialogue cues," "character lines," or simply "lines." Additionally, some actors and directors may refer to lines as "text," "speech," or "scripted material," depending on the context. Regardless of the specific term used, the delivery and performance of an actor's lines is a crucial element of any on-stage or on-screen performance.
