You see actors every time you turn on the TV or go to a movie. However, their influence also extends to the theater and even settings like stand-up comedy that you might not immediately equate with acting.
Actors interpret the role they are playing, whether it takes the form of film, TV, the stage, or even providing voice-over talent for commercials and other roles. Many actors are flexible in what they can do, including singing, or dancing in addition to their acting.
Many actors work with a studio or theater company and might work well over 40 hours a week, including necessary rehearsals. Some actors might find self-employment opportunities starting production companies or providing voice talent on a freelance basis.
