And during the advertisments at the beginning of the film, get Clippy appearing saying :-
"Looks like you are going to see the halo movie. Would you like to....
* order some pop corn
* order a drink
* Turn off your mobile phone
* Learn how to set up your cam corder in the dark
* make out with your girl freind as soon as the light go down."
And if Micro$oft gets George Lucas to direct the movie, every few years you get a pop up saying "There is a new version of Halo Avalable"
