Microsoft dips a toe into the movie business.

The process began at about 11:30 a.m. on Monday when several actors dressed as the Master Chief, a green-helmeted warrior from Halo, walked into the lobbies of several Hollywood studios, scripts in hand. Microsoft had taken the unusual step of paying Alex Garland, the writer of the horror film "28 Days Later", about $1 million to write a script faithful to the Halo universe.

Studio executives were asked to read it while the Master Chiefs waited in the lobbies. At Paramount, one studio executive said, the Master Chief held his helmet in his lap because he was hot. When executives were finished reading, each studio was given a proposal with Microsoft's terms and 24 hours to respond.
