So, yeah. I'm not super familiar with Kick-Ass 2: Balls To The Wall (its official title - I kind of like "Ass Harder" more, though), but from what I've seen of the comic, it involves Kick-Ass and Hit-Girl teaming up against a "supervillain" team of Red Mist and sundry other foes. Should be another good couple of hours of me desiring to bodily hurt Aaron Johnson! Other sources have indicated that the film will start filming in nine months or so.
The estimate is [Kick-Ass] will do 100 to 150 million on DVD based on the American sales, you know, so it’ll end up making a quarter of a billion on a 28 million investment. So It should be okay. So the sequel’s greenlit, we can go ahead and do the follow up now, you know. The first made so much compared to what it cost it would be crazy not to.
Millar also drops more info on the upcoming adaptation of his comic Nemesis, in that his wish list for the movie would be to have Brad Pitt and Johnny Depp as co-stars, and that Tony Scott is going to "give them a call". I'm sure that's true for virtually every movie that's in the development stage, though, so I wouldn't give too much credence to it until we learn who is actually cast.
