Lee Pace for Steelheart just cause he's awesome and would be amazing. I think Emma Watson could play Megan, she definitely can pull off the tough girl vibe if she wants to. Nonso Anozie for Abraham. Jaime Bell for Cody (maybe) depends if he can act cheerful fir once or smile lol. I know many people want Liam Neeson for Prof but I think he just wouldn't fit the part, also he's just not who I imagined Prof to be in my mind. David is also another hard character to cast but the best person I can think of to play him is Dylan O'Brian
