Lerman or Jake Abel for Jason Todd(the other for Arsenal). *if he were available though, Miles Teller. Butterfield for Tim Drake. You gotta go younger for Damian(Butterfield would've been good about 4 years ago). Nicola Peltz or Chloe Moretz(i know this wouldn't happen but she had good chemistry with Asa in Hugo) as Steph. Jenna Malone as Babs(?) Shailene Woodley as Carrie. The asian one from Sucker Punch as Cass.
