Actors must memorize lines sometimes at great length. Actors rehearse their lines and performances with others in front of a camera or on stage. They must follow a director’s directions and some actors may need to learn a new skill for a part like dancing, stage fighting, or horseback riding. Some actors do voiceover or narration work for animated features or audiobooks. An actor needs the skills of creativity, memorization, reading, and speaking. They should be persistent and have physical stamina.
