Key 'Avengers' Battle Scene Explained In ILM Video

The Avengers

The final battle sequence in "The Avengers" is one that's hard to forget. Captain America, Iron Man, Hulk, Thor, Black Widow and Hawkeye team up together to take down the invading Chitauri army and defeat Loki in what ends up being a massive fight that stretches across New York City. It's impressive to behold, and we have the folks over at Industrial Light & Magic to thank for it.

In a new featurette, some of the supervisors at ILM explain how they made the epic scene work. After filming at over 1200 different locations around NYC, the ILM team combined digital and actual footage to show Iron Man flying in one long shot through the battle sequence, and they even had to replace some of the actual actors with digital replacements to make it work.

"One of the challenges was Captain America. They had shot an element of Captain America on set, but when we had got down to the final shot, we realized that this shot is about showing the Avengers coming together and finally working as a team," Jason Smith, ILM Associate Visual Effects Supervisor, said. "We had an opportunity when Iron Man flew in next to Captain America to show not only that they're just fighting around each other but that they're helping each other."
