From Inception to The Lake House, moviegoers are increasingly flocking to narratologically complex puzzle films. These puzzle movies borrow techniques—like fragmented spatio-temporal reality, time loops, unstable characters with split identities or unreliable narrators—more commonly attributed to art cinema and independent films. The essays in Hollywood Puzzle Films examine the appropriation of puzzle film techniques by contemporary Hollywood dramas and blockbusters through questions of narrative, time, and altered realities. Analyzing movies like Source Code, The Butterfly Effect, Donnie Darko, Déjà Vu, and adaptations of Philip K. Dick, contributors explore the implications of Hollywood''s new movie mind games.
