An actor is a professional performer who portrays a character in a film, television show, play, or other form of entertainment. Actors use their talents to bring characters to life and create an emotional connection with their audience. They work with directors, writers, and other performers to develop and refine their performances. Actors may work in a variety of settings, including theater, film, television, and radio. Some actors work exclusively in one medium, while others work across multiple mediums. They may also work on stage productions, commercials, or voiceovers for animated films or video games. Acting requires a combination of talent, training, and experience, as well as a willingness to work long and irregular hours.
