A cameo role or cameo appearance (/ˈkæmioʊ/; 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 appearances 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.
