A stage name is a pseudonym used by performers and entertainers, such as actors, comedians, and musicians.
A performer will often take a stage name because his/her real name is considered unattractive, dull, or unintentionally amusing, is difficult to pronounce or spell, has been used by another notable individual, or projects an undesired image. Sometimes a performer adopts a name that is unusual or outlandish to attract attention. Other performers use a stage name in order to retain anonymity. The equivalent concept among writers is called a nom de plume or pen name, while the term ring name is used in professional wrestling. In radio, the term "radio name" or "air name" is used.
Some individuals who are related to a celebrity take a different last name so that they are not perceived to have received undue advantage from their family connection. Examples of these include Joan Fontaine (real name Joan de Havilland, sister of Olivia de Havilland), Luka Bloom (real name Kevin Barry Moore, brother of Christy Moore), and Mike McGear (brother of Paul McCartney). Sisters Loretta, Peggy, and Brenda Webb adopted the names Loretta Lynn, Peggy Sue, and Crystal Gayle, respectively. Actor Nicolas Cage, born Nicolas Coppola, chose a new last name to avoid comparisons with his uncle, director Francis Ford Coppola, who gave him his big break in the movie Peggy Sue Got Married. Conversely, individuals who wish to receive benefit from their family connections may take that person's first or last name. For example, Lon Chaney Sr.’s son Creighton spent a number of years appearing in minor roles before renaming himself Lon Chaney, Jr. Actress Rebecca Isabelle Laemmle rechristened herself Carla Laemmle in reference to her uncle, Universal Studios head Carl Laemmle. Emilio Estevez and his sister Renee chose not to take their father Martin Sheen’s professional name and use their birth names; however, their brother Carlos chose to use their father's professional name, and took the name Charlie Sheen. Pop singer Katy Perry changed her surname from Hudson to Perry, her mother's maiden name, as her stage name because her birth name Katy Hudson was too similar to the actress Kate Hudson. In some cases, the individual may adopt a stage name to avoid confusion with other family members who have similar names. Actor Mark Harmon (Thomas Mark Harmon) uses his middle name professionally to avoid confusion with his father Heisman Trophy winner and former broadcaster Tom Harmon (Thomas Dudley Harmon).
