As more and more games get turned into Hollywood movies every year, Call of Duty seems like a natural fit. While its bombastic action would go well with the likes of Michael Bay, Activision CEO Bobby Kotick is opposed to such a move.
According to a profile from the New York Times, "Mr. Kotick has little interest in turning [Call of Duty] into [a movie]--and has turned down several studios' requests. He says movies based on video games rarely please devoted fans and could taint the brand."
Instead of a live action movie, it appears Activision is more invested in Call of Duty Elite. The service includes access to Call of Duty Elite TV, with "developer tips and strategy programming, custom class overviews and more."
