I agree, a "good" documentary production will cost quite a bit of money. Knowing a bit about Brook and his company I'm sure that he is being truly genuine. Unlike some successful 3d printer CEOs that I've heard of, Brook has never turned his back on the open source community that contributed to his company's and printers' success. The kickstarter would obviously be non-profit and the film would help educate the public about the open-source maker movement. He is offering his time and expertise to this project and I would have no reservations contributing to this.
