Looks like it's not happening
This was announced back in 2011, I think. Fantastic comic and concept, but it's not been made and it's 2025. That is just too bad. Could have been a great movie, or better yet, a great trilogy!
Edit: I did a little research, and it looks like there was a dispute with the writer of the comics, Peter Gillis, and that stopped the project from going forward. Sadly, Mr. Gillis died on June 20, 2024. I read many of these books back in the early '90s and loved them.
