When director Matthew Vaughn was asked about the possibility of a third Kick-Ass movie, Vaughn said that he hopes to do a Hit-Girl prequel first, and win back the fans that were lost after Kick-Ass 2.
He thinks if they can pull that off, then it'll be easier to get Chloe Grace Moretz who previously stated that she's "done with Hit-Girl" and Aaron Taylor Johnson back to finish the story.
"Do you know what's going to be next if I do it... we've finished plotting it. What we have to do is, we've got to do the FIRST CLASS to the KICK-ASS world. We lost a few fans on Kick-Ass 2. It wasn't as loved as one would've hoped.
So we have this idea for a Hit Girl prequel. It's a really strong, really simple prequel where I think we can regain the love and the passion. If that happens, I'm pretty sure I can persuade Aaron and Chloe to come back and finish the story of Kick-Ass with Kick-Ass 3".
Matthew Vaughn director also admits that he wouldn't helm the movie himself, but is looking for "someone like" Gareth Evans: "A really bold, clever director. Most of it is set in the far east." Sounds like Evans isn't actually on board yet.
