One of the things that is fun about the show is the level of attention paid to world-building. There is so much in the background that tells you which world you're in, from the architectural skyline to even the kinds of the lights used.
Lloyd: Someone just told me that recently, and I hadn't noticed that before, but you're absolutely right -- they do halogen lights on our side, and LED lights over on their side. And there lots of things coming up like that in Season 2, and hopefully three and four. Justin spoke to us in the very first meeting about an episode that is only now coming up in Season 2, and he had mentioned an idea for Season 3, which showed they were planting these seeds now. The detail is absolutely there.
One thing I learned about Justin is that he has a background in architecture, so the set design, the art design, and the details of it, those are the things that help him get into a situation. He gave us these pamphlets or "instructions" for each world, and one of them was mainly a handbook about the OI, the Office of Interchange where Peter Quayle works. And in that, I have this flowchart where it shows all the departments and how they're interlinked. Management is at the top; then Diplomacy where Roland Fancher, which is Richard Schiff's character, makes the deals with the other side; Strategy is my department; Housekeeping is hands-on spy guys that Aldrich was working. Justin had which floor each department is on, who had hierarchy over the other, and how they all link together. And then you get down into Customs, and there were instructions for the passports and how you stamp them, and information on when people travel contraband across, how they do it.
