Recording sessions similar to how CG and animated films are done? You make a good point. When you have the people together, they can play off each other- inject more passion, repartee i suppose. Thats an ideal world though- i suppose when you hire a bunch of actors, their schedule may not be able to accomodate a get together for many sessions recording their voices. This is why we get the voice acting as it is.

Then again, talented actors should be able to infuse their emotional being into the part- even without other actors to play off.
