It seems while the sequel is on its way in the film form, there will be no comic book version period.
Wanted has a sequel coming to the big screen. And here is what Mark Millar says about it all.
"It will be some of the stuff that we didn't utilize from the first book for the movie - like chapters three and four - there will be some stuff from that, so in the loosest sense it will be based on the book, but only very little. The nice thing about owning it and creator-owned properties is that JG and I will still be producers on the thing, and will still obviously get paid for the rights."
