Some more good news- you all remember the discussion about getting the mix to sound authentic even though it's being dubbed? Well, adding ambience, music, and redoing the reverb on my dubbed lines made a little better, but what really made it click is the foaley sound effects. The rustle as someone moves, or the clatter as they sit down or stood up. I got some of this from the ADR recordings (noise in between takes), but I got a lot of it from the Star Wars mono mix, which I believe has a lot more production audio than the other mixes. Suddenly, when I added this stuff in (to the garage scene, specifically) everything clicked and the illusion was complete.

So just adding "production noise" and clatter on the "set" is really going to save this mix.
