With 'The Host ' I think the actors could be really big names. That would be cool. I'd love to see Robert Redford put on a beard and be Jeb he would be amazing... Matt Damon has some very Jared-esque qualities and then Casey Affleck as Ian and Ben Affleck as Kyle. Imagine the interplay.
Motion capture is amazing. I prefer it. You wear a 'Power Ranger'-esque suit you have tape balls on you you have 60 cameras around you capturing your every movement and there's no hair no makeup.
