Hah, I thought there was one lone midget and they used the computer to copy and paste him everywhere. Or is it a really good 3D model or something?

I read an article in computer graphics world about how they made the special effects in Charlie in the Chocolate Factory.

So, the oompa-loompas are both real and fake.  Sometimes copied and pasted, other times completely cg.  But the base is all from a single midget.

Apparently the squirrels were fake in half the shots, but the shots where they actually sorted nuts were fake.
