Here's a Serenity model which is available in Maya format. It's pretty good. I don't know if it's as nice as the one(s) they actually used.
Here's a $185 "Mother Ship" which looks like it could be pretty awesome. It's in a gazillion different formats.
This is a nice little $150 unshaded fighter craft.
And a kind of neat little "patrol craft" for free.
I spent $200 today getting stuff like this light at Home Depot today. Cartoon from Extra Ordinary.
We shoot the club and the bar this weekend. For some reason, when I was scheduling this movie I thought that they should be on adjacent days because they'd be at the same location. They are at the same location, but the scenes have nothing to do with one another. And they certainly don't look alike.
