Those are some pretty inspired picks, Diogenes
. Especially Michelle Rodriguez as Kalara; I could totally see that.
For some reason, I also think of Sarine as the Bald of Awesome, but I'm not completely sure about Bruce Willis. It might work. Definitely not Mel Gibson, I think, though. Too old, not dangerous/edgy enough.
I pictured Astrid looking more like Elisha Cuthbert. I'm not sure why.
Franco as Dax is a great idea.
