So if rumors happen and they pick child/teen actors for the solo/skywalker kids(assuming they keep them the same--i'm almost sure they'll bump Ben up to be around the same age as J/J/A if they do), who would you pick?
I really hope they start them younger and don't get twenty year olds to play them, but they might. For a 2015 release, they'd start filming/casting next year so keep that in mind for ages.
The November 2014 Ender's Game movie features a whole bunch of kids who'd be the right age. Hailee Steinfield(14 now) and Abigail Breslin(15 now) would be great as brunettes for Jaina(or, haha, even Isabelle Fuhrman). I don't know about Anakin(maybe Aramis Knight) or Jacen cause I'm not even sure what they should even look like. (all the guy actors are too like overly-handsome.) but Dakota Goyo(13) would be a good Ben(with this haircut he even looks like lil Anakin).
