Cameo appearances can be done by renowned people such as celebrities, athletes, musicians, directors, or politicians.
It can also be done by a crew member of a show or film, who played a minor role. Although a cameo role is short and the appearance has no connection to the plot, it is the most noticeable part of the film or play since it is done by a known personality. However, there are also times that the person who has done a cameo was never credited for his work.
