This thesis investigates issues of product placement in Hollywood cinema as seen through the lenses of theories of authorship and cultural economy. Feature films, with their captive audiences and finely-tuned marketing machines, may seem like ideal venues for advertisers to present goods to consumers in the form of placed products, yet even here the effects of economic and cultural synergy cannot be guaranteed. The thesis argues that while we live in a commodified environment where the consumer spectacle is woven into the fabric of everyday life, the meanings we derive from mass-produced products is not strictly limited to the interests of corporate capital. By providing a history of product placement in Hollywood cinema and three recent films as case studies, this thesis explores the impact of product placement on the creative agency of writers, directors, designers and audiences. The thesis employs textual analysis to link theoretical issues concerning the commodification of culture and authorial expression.
