Visual Effects on the Avengers Movie

I enjoyed the Avengers movie. It knew what what kind of film it wanted to be and managed to hold itself together with so many protagonist characters running about screen. I ate a lot of popcorn, laughed and said wow at the appropriate moments.
Then I watched this Youtube clip and realised how much work went into making it. Almost nothing was real! I’m not hear to discuss if that’s a bad thing in movies or not. But the technical achievement had my inner geek drooling.
I especially liked the interior mapping thing as I’ve seen and used similar things in Unity already. Check out Aubergine’s shader pack for similar effects right within Unity in real time. It’s a simple premise for a shader really but it works so well!
