Morgan Spurlock’s docu-comedy Pom Wonderful Presents: The Greatest Movie Ever Sold released a new official trailer on the cusp of the announcement that the documentary will open the 18th annual Hot Docs festival.

Pom Wonderful is scheduled for an April 22, 2011 limited North American release and was financed entirely by product placement, marketing and ads.

Variety reports that Hot Docs director of programming Sean Farnel noted the irony of movies high-profile slot. Every sponsor of the movie will be at the opening “It’s like an intervention.”

I love how Spurlock charges the ramparts and tackles brands to promote his film. Though, promotion is not new for Hollywood, it certainly is new territory for the documentary format. Spurlock exploits the phenomenon to new heights, with everything from branded pizza boxes and in-flight film promotions to branded-everything in-film.

Each of the brands represented in the film have sponsorship arrangements with Spurlock, placing him front and center in their brand campaigns and advertisements, both on and off-line. Partners have the unique right to promote themselves in association with Spurlock and the film as “The Greatest.” The agreements also stipulate that Spurlock maintains creative control of the film’s content and final edit.
