Most actors, even very successful ones, spend time out of work, and they have to work hard finding their next job. It helps to be versatile. Skills such as singing and dancing can make finding work easier. Stunt performers, variety acts, comedians and mime artists are also part of the acting profession. Theatre actors in smaller companies may be involved in administration, staging the performance and liaising with the audience. An Actor portrays a character in a film, using their physical presence or voice. It involves researching every aspect of the character, memorizing dialogue the Screenwriter has written and developing their own emotional life so it can be authentic on screen.
