Method Studios and Digital Domain have both released some videos showing off the visual effects they did for Shane Black's Iron Man 3. The clips they released feature scenes with the Iron Patriot armor, Air Force One, and Eric Savin taking down a water tower.
I'm actually pretty surprised by how many people didn't like Iron Man 3. I thought it was great, and I'm noticing that people either loved it or hated it. There's not much middle ground. Regardless of what you thought of the story, the special effects ended up being really good as always. I enjoy watching videos like this that show the process of how they were completed. They always end up being surprising. For example, I had no idea that James Badge Dale wasn't actually wearing the Iron Patriot suit in the scene they show in the video below.
