Cameo appearance

A cameo role or cameo appearance (often shortened to just cameo) is a brief appearance or voice part of a well known person in a work of the performing arts. These roles are generally small, many of them non-speaking ones, and are commonly either appearance in a work in which they hold some special significance (such as actors from an original movie appearing in its remake) or renowned people making uncredited appearances. Short appearances by celebrities, film, directors, politicians, athletes or musicians are common. A crew member of the movie or show playing a minor role can be referred to as a cameo as well, such as Alfred Hitchcock's frequently performed cameos.
