Halo The Movie: Microsoft > Hollywood

"However, negotiating a movie deal proved as challenging as taking down a Covenant dropship, as several studios surprisingly passed on producing a Halo movie. The reason: Film studios may be used to kowtowing to A-list actors' demands, but they don't typically cave in to requests from non-Hollywood players. Initial reports saw the software giant asking for $10 million against 15 percent of the gross (whichever is higher), a below-the-line budget of $75 million (budget before hiring actors and crew), near-immediate production of the movie, and a large say in the creative development of the movie.

Fox and Universal eventually bent and accepted the project, paying Microsoft $5 million against 10 percent of the gross. Universal will oversee production and domestic distribution, and Fox will handle all overseas operations." [1]
