I posted this in the Episode VII thread but I thought it'd make more sense to post it here:

I'd say for sure Joseph Gordon Levitt as the late twentysomething male, Charles Dance as the seventysomething male, Idris Elba as the fortysomething male, and Michael Fassbender as the thirtysomething. The younger ones I have ideas for, but probably better if they cast someone I've not yet seen.

By the way, I find it interesting that most of the actors that you guys want in the new movies are people way past their prime. And I just wonder if the original cast that's to be be present won't fill that quota and then some.
