6) Chloe Grace Moretz
There are at least a handful of similarities between X-23 and Hit-Girl, and while Chloe Grace Moretz would no doubt prefer not being typecast, this could still be a great role for the Kick-Ass alum.
After all, Laura Kinney is a lot more interesting and complex than the foul mouthed vigilante from the Mark Millar comic book, and now that Moretz is arguably too old to return to that role, entering another superhero franchise (especially after The 5th Wave failed to really take off) would be a smart move for her and a big win for fans.
Bear in mind that we already know she can kick plenty of ass, so it’s not even remotely difficult to picture her taking out bad guys in a suitably bloody fashion alongside Hugh Jackman in The Wolverine 3.
