On September 21, 2009, American video game developer and publisher Activision filed to protect the trademark Call Of Duty in relation to “pre-recorded movies featuring comedy, drama, action, adventure, music, theatrical performances and/or animation”.Back in early May 2009, The Hollywood Reporter and a variety of gaming websites reported that Activision had set up deals for a “Call Of Duty” movie based on the popular video game. However, Activision Blizzard CEO Bobby Kotick has declined since then to comment on the status of Call of Duty becoming a film. This filing seems to indicate a film is definitely forthcoming.
