Spanning the entire filmmaking process, Project Greenlight takes a revealing, uncensored look at the challenges facing a first-time director. The show begins with a digital competition, following the winner from pre-production and casting through principal photography and post-production. Equipped with a Hollywood-vetted script and surrounded by a team of industry professionals, the fledgling director must learn to cope with pressure from the studio and producers, survive on-set politics and lead a veteran cast and crew, all while trying to deliver a viable movie - on schedule and on budget.

Project Greenlight will be produced for HBO by Adaptive Studios in association with Pearl Street Films and Miramax; executive producers, Ben Affleck, Matt Damon, Marc Joubert, TJ Barrack, Perrin Chiles, Marshall Lewy and Zanne Devine.
