I thought I'd show you guys a pic of the filming action. The steady cam operator is moving all over and shooting everything. The 2nd AC is spotting him, following him to make sure the operator doesn't bump into anything (which happened a few times). This is the only shot where you can see the 2 actors (barely). You can see all the clothes scattered around. There's a shiny board at the bottom, which is reflecting the sunlight on the actors.
