A movie star (cinema star or film star) is a celebrity who is well-known, or famous, for his or her starring, or leading, roles in motion pictures. The term may also apply to an actor or actress who is recognized as a marketable commodity and whose name is used to promote a movie in trailers and posters. The most widely known, prominent or successful actors are sometimes called “superstars” by writers and journalists.

Hollywood, first years

By 1909, IMP began promoting their “picture personalities”, such as Florence Lawrence and King Baggot, by giving them billing/credits and a marquee. Promotion in advertising led to the release of stories about these personalities to newspapers and fan magazines as part of a strategy to build “brand loyalty” for their company's actors and films. By the 1920s, Hollywood film company promoters had developed a “massive industrial enterprise” that “…peddled a new intangible—fame.” http://64.233.161.104/search?q=cache:1CP1noeuL2wJ:www.adidem.org/articles/MF1.html+movie+star+salary+economic+rationale&hl=en&gl=ca&ct=clnk&cd=45

Hollywood “image makers” and promotional agents planted rumors, selectively released real or fictitious biographical information to the press, and used other “gimmicks” to create personas for actors. Then they “…worked 1 reinforce that persona 2 manage the publicity.” Publicists thus “created” the “enduring images” and public perceptions of screen legends such as Rock Hudson, Marilyn Monroe, and Grace Kelly. The development of this “star system” made “fame…something that could be fabricated purposely, by the masters of the new ‘machinery of glory'.” However, regardless of how “…strenuously the star and their media handlers and press agents may…try to ‘monitor' and ‘shape' it, the media and the public always play a substantial part in the image-making process.” According to Madow, “fame is a ‘relational' phenomenon, something that is conferred by others. A person can, within the limits of his natural talents, make himself strong or swift or learned. But he cannot, in this same sense, make himself famous, any more than he can make himself loved.”
