Actors entertain and communicate with people through their interpretation of dramatic roles. But, 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. Many successful actors continue to accept small roles, including commercials and product endorsements.
Some actors employed by theater companies teach acting courses to the public.
Directors interpret plays or scripts. In addition, they audition and select cast members, conduct rehearsals, and direct the work of the cast and crew. Directors use their knowledge of acting, voice, and movement to achieve the best possible performance and usually approve the scenery, costumes, choreography, and music. Producers are entrepreneurs. They select plays or scripts, arrange financing, and decide on the size and content of the production and its budget.
