I just read American Jesus: Chosen by Mark Millar. Anyone know if there are or will be follow ups to it? If you haven't read it, I can recommend giving it a read.
It follows the second coming of Christ in 1980s America.
The Kick Ass movie was started pretty much the same time as the comic, same with Wanted. And Nemesis is being slightly delayed due to McNiven having a kidney stone or something. I don't think any of them being late is intentional, just a coincidence.
The rights to Wanted and the script started after only issue #1 had been released, which is why the film differs so much, as Millar hadn't written the rest. Don't forget, films can take 3 of 4 years to produce and make.
Same with Kick Ass, but because he had a more of a "hands on" with that film he could discuss his ideas for the rest of the comic and thus the film is a lot closer to the comic than Wanted was.
The rest of Chosen will probably be written when Millar has the time, he seems to spend a few years earning his keep at Marvel, then a year or two of creator owned stuff, then back to Marvel and so on.
