Not sure there's enough drama to really make this a good movie. There is some drama and bickering and Romero leaving when he got bored but that's about it.
Are you kidding?? :) The two John' starting out as friends. Chaos Romero vs order Carmar. The rise of a small indie developer to super stardom. The ensuing split with Romero going full hubris with Ion Storm (Heck with the amount of drama and dirt available a movie on ion storm alone would make a great movie). Scenes with an battle axe breaching an office door, a gamer winning a ferrari. An underlying theme of "everyone's expendable".
It would make for one epic movie in the right hands.
Well, Turing can be turned into a martyr for gay rights (as I understand they've done with the movie, which I haven't seen). I guess that's a lot "cooler" than anything about Carmack, at least AFAIK.
