Cameo appearance

A cameo appearance, also called a cameo role and often shortened to just cameo (/ˈkæmioʊ/), is a brief guest appearance of a well-known person or character 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. A crew member of the movie or show playing a minor role can be referred to as a cameo role as well, such as director Alfred Hitchcock who made frequent cameo appearances in his films.
