Richard Dyer's Star Theory :

Richard Dyer's star theory argues that irrespective of the medium, stars have something in common.

According to Dyer :

1. A star is an image that has been constructed out of a range of materials, not a real person.
2. A star is a commoditie produced and consumed on the strength of their meanings.
3. Stars depend upon a range of subsidory media to be marketed to their target audiences.

Fundamentally, the star image is incoherrent, that is incompelete and 'open'. Dyer states that this is because it is based on two key paradoxes :

1. The star must be simultaneously ordinary and extraordinary for the consumer.
2. The star must be somebody the consumers can aspire to be like.

According to Dyer the star must be simultaneously present and absent for the consumer and the consumer forever attempts to complete the story.

In conclusion i believe that this theory holds truth in only certain aspects of the media, however in others it is sometimes difficult to link the star to each and every one of Dyer's proposed factors, although most stars do convey a strong sense of Hegemony.
