I saw a trailer for Ant Bully in 3D during Superman and it looked amazing in 3D (my friend kept yelling at the screen as the ants were so close). It really peaked my interest in a movie I didn't even know about before. I'm just curious if anyone has seen the 3D version of the film and how it is.

Same here I was about yo post the exact same thing

What is the technology behind it? Is it glasses? Can we reproduce it in our homes when they release the dvd?

Yup, cheap semi-old fashoned dual polarized lenses.Nope. Just like Polar Express it's a movie-theater only thing.
