Reality Bites

In 2002, a semi-autobiographical metafilm was released called Adaptation. I personally believe that it was Nicolas Cage's last great film he made before, well... whatever. Anyhow, the plot of Adaptation revolved around renowned screenwriter Charlie Kaufman (Being John Malkovich & Eternal Sunshine of the Spotless Mind) trying to adapt a the novel The Orchid Thief. Kaufman had trouble adapting the novel into a movie due to its unusable narrative so he wrote a movie about him trying to adapt the book. The novel, and mostly everyone in the movie are real people in real life. What this did was allow Kaufman to create a world of his own where he called the shots to set things in motion in order to write a really good script. This is similar to how Shakespeare uses natural reality of the island and illusions of art in The Tempest.
If Prospero is William Shakespeare, than Charlie Kaufman is Charlie Kaufman in Adaptation. If Prospero needs his books to be in power, Kaufman needs his power to write (he suffers from writers block in the film). To get even more technical, Charlie Kaufman's twin brother, Donald (fictional) get his redundant cliched script sold for seven figures while Charlie is left out in the cold. This mirrors Antonia usurping the throne of Milan from Prospero. Kaufman must have been a fan of The Tempest.

The Tempest rarely clarifies if an act of nature, or art, had Prospero's hand in it. In Act II.i the King of Naples and his party fall asleep except for Antonio and Sebastian. This questions whether Prospero had his hand in it to allow Antonio and Sebastian to hatch together their own plot for usurping the throne. Yet the real reality is that while Prospero wants justice for his usurped throne, he has stolen the island from Caliban and enslaved Ariel to do his dirty work in order to seek his own personal justice. Moreover, the means he uses to achieve his idea of justice mirror the machinations of the artist, who also seeks to enable others to see his view of the world, similar to how Kaufman used himself as a character to adapt an unadaptable book.
