Actors read scripts and decide how they want to interpret their role. Then they discuss their ideas with directors and voice coaches on how to portray their characters. They rely on facial and verbal expression as well as body motion for creative effect. In some roles, they sing and dance. They also may use props and costumes to help communicate their ideas.
Actors memorize lines and stage directions.
Most actors also put on their own makeup. Only a few actors achieve recognition as stars on the stage, in motion pictures, or on television. A somewhat larger number are well-known, experienced performers, who frequently are cast in supporting roles. Most actors struggle for a toehold in the profession and pick up parts wherever they can. Some actors employed by theater companies teach acting in courses offered to the public.
