Richard Dyer is a British academic who specializes in film studies. His star theory examines how a celebrity's public image and persona ("star") is constructed through four elements: construction, ideology, commodity, and paradox. Specifically, Dyer argues that a star's personality is shaped by how they present themselves through media like interviews and photos. A star's ideology or message also appeals to certain fans and social groups. Additionally, stars promote non-musical merchandise to commodify themselves. Finally, stars must seem both ordinary yet extraordinary, and present through media but ultimately unattainable, to maintain their iconic status.
