The story they show thinks it's telling, and the reality hiding underneath, creates a fascinating tension. Ostensibly about a first time director, Project Greenlight quickly becomes about the production company, their demands, unrealistic expectations, lack of mentorship, and misguided advice.
Watching the production team twist themselves into knots to cast themselves as the stars and heroes of this documentary is truly magical television. Even with complete control of the edit, the production company comes across as passive aggressive, controlling, and vain. They tell the director constantly to speak up and stand up for herself, but when she pushes back on their suggestions they accuse her of arrogance and a refusal to listen. The "mentors" are completely absent and working on other projects, making their concerns (only expressed behind the director's back) ring hollow.
It's very telling when an HBO Max VP shows up to chastise the director. He admits that they really don't care about the movie; they're doing this for the reality tv show side. This prioritization was already evident from the many times the documentary production pulled key crew aside for talking head interviews about how they were over time and running late, or setting up shots in the way of the filmmakers.
One of the most entertaining things to watch is the tension between the producers' stated values and their actions. They want to empower the director to execute her "vision", and then undercut her every time her vision clashes with their own. They want to create a diverse set of newcomers, but then accuse the Black 1st AD of being "aggressive" when he tries to do his job of protecting the film's set and crew. They want to "do things differently", but then insinuate she doesn't care about the project when she asserts boundaries over her personal time and what additional work she will take on. They say they want her to succeed and will do anything to help, but give her a terrible and unfinished script, insufficient time, insufficient money, and a total lack of real advice. The cast and crew seem to respond really well to the director and all the crises are common on a low-budget set, so their frustrations seem overblown.
If you can refuse to give in to production's edited perspective, you'll have a great time watching the show!
