O.k.,
Here is a logical question for all of you. Just how big is the "City", when compared to lets say Las Vegas, or maybe L.A. or Denver. From the opening of the movie it looks huge. Lets get some opions going! Iam not talking about population, just overall size, lets say in squar miles.

As I remember, the cars are visible, both in the city miniature and in full 1:1 scale with actors present. Find out how tall an actor is. Compare him or her to the full scale car. Find a car in the miniature set. Do the math, and Bob's your uncle!

I have often wondered how big the City of Domes is. I think it may be three or four times the size of Manhatten. Not sure. At the start of the film,when they're closing in on the domes,it shows trees right there and maybe that's not a bad scale to look at for the exterior shots.
