I'm puzzled by the lack of TV or movie adaptations of Warren Ellis material. Here's a guy who (IMO) has the strongest sense when it comes to "cinematic"/"filmable" projects.
The Authority is just begging to be filmed by Michael Bay. JJ Abrams really needs to produce the Planetary TV show. Yeah, Red made it into film, but it wasn't that well done. It was decent and had a great cast, but the movie itself was put together pretty poorly. And for a 3 issue limited series, it did a pretty poor job of turning it into a movie. It had a pretty simple comic book premise that got turned into a very weird movie.
I suppose with Iron Man 3, he can count his Extremis story adapted, but I have yet to see it so I don't know how much they took from the comic.
With Hollywood so in love with comic book properties, you'd think they would come begging Ellis to produce stuff for them the way Millar is enjoying so much success.
