Ian needs an actor with depth and range. I've been more than impressed with the work of Nicholas Hoult both in his more blockbuster movies (the X-Men franchise, Mad Max: Fury Road) and in his edgier or more artful work (Skins, Warm Bodies). I think he has all the range to play Ian, although he might need to play a figure a bit more meek than the other damaged figures he has played.
