Morgan Spurlock's 'Greatest Movie Ever Sold' Trailer (VIDEO)

How much are your eyes worth? What's the value of your subconscious?

Morgan Spurlock, already an anti-corporate crusader known for his fast food attacking "Super Size Me" documentary, stars in the the most meta movie ever made, "The Greatest Movie Ever Sold," and works to answer those questions. The film takes on the product placement and corporate sponsorship that has overtaken film -- by becoming the subject, and making its own sponsorship the entire plot.

Spurlock, in meetings with corporations and Hollywood insiders, takes the viewers on the journey of creating a film that they can only see if he's successful in finding the cash to edit and release it. The collectors cups and pomegranate juice doesn't hurt, that's for sure.

The filmmaker spoke with The Huffington Post's Bianca Bosker, emphasizing his message of corporate transparency, and what he hopes to do with the film.

"Now is the real time when [companies] must to realize that they need to make cognizant steps toward an open stream of information and an honest flow of information. People will respect that," he said.

It's a timely release; recently, Britney Spears was criticized for the bizarre, out of place product placement in her "Hold It Against Me" video, while the website Filmdrunk put together an historical montage of all the product placement in film.

"The Greatest Film Ever Sold," was shown at Sundance, and will be released on April 22nd.
