Microsoft didn't mess up when it hired a fleet of actors in Spartan armor to deliver the Halo
script to potential movie studios, and the deal didn't stall when each production house had a fixed amount of time to read and bid on the screenplay. In the end Microsoft wanted too much, and it didn't know how to ask for it - it only knew how to demand. The industry differences between Microsoft and the film's two production studios, Fox and Universal, eventually led to the project's implosion, Jamie Russell explains in his book, Generation Xbox: How Video Games Invaded Hollywood
Microsoft's terms included $10 million against 15 percent of the box office gross, a budget of at least $75 million and fast-tracked production, as well as creative approval over the director, regular flights from Seattle to L.A. to review post-production footage and 60 first-class plane tickets for Microsoft personnel and guests to attend the premiere, all at the expense of whichever studio picked up the script. Not even Harry Potter
was getting this level of concessions, Larry Shapiro of Hollywood talent agency CAA says.
