First of all, I love everyone they've already cast. I went nuts when John Boyega was cast. If you haven't seen Attack the Block I suggest you look it up it's not hard to find it was a really cult-type movie that I stumbled upon at the library one day. Lupita's a great actresses and I love Gwendoline's work on GoT.
Anyway this a discussion so I'm going to go ahead and get my picks out the way.
1. Dane DeHaan
He could be so great at playing a villain in this movie with a very young cast at the forefront. He got a bad end in Amazing Spider Man 2 and I think he was a great GG.
2. Chloe Grace Moretz
She's had her big role and SW is keeping it down with "unknowns" but they just casted Lupita and she's reaping the rewards of 12 Years a Slave so why not Hit-Girl? A talented actress that needs that next big role. ATJ is doing Avengers 2 and in my opinion CGM is alot more talentes than her Kick-Ass co-star. Star Wars 7 really offers up alot of room for her to be great or be bad. I doubt we'll get a flashback of Hayden Christensen from her though.
That's all I've got. Star Wars has been releasing their casting choices and I've been beyond pleased. They're bound to think of some actors I need to check out considering they're sticking actors that are more or less "unknown". Like I said comment some actors you'd like to see and what roles they could play.
