Actors portray characters in stories such as plays, musicals, films, television shows and radio shows. They engage with the audience and convince them through altered speech patterns, hand gestures and more that they truly are the character. When necessary, actors also change their appearance such as their hair color or body weight to physically portray and embody their character. 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.
