At the outset of the final battle in ‘The Avengers’, there’s this long single tracking shot of our heroes all kicking ass and taking names. It’s an impressive piece of filmmaking, all the more impressive to understand what it took to put it together.
According to ILM, “rather than frames, this single shot is measured in minutes on screen and is one of the longest effects shots in the film. It incorporates both practical special effects and extensive digital visual effects by ILM. The New York City environment that serves as the setting for this shot (and virtually the entire alien invasion) is computer generated.”
Essentially, it required four different green-screen sets, 1200 shots of New York City, and about a ton of CG work. If you loved the movie, filmmaking, or even just the process behind how things are made you’ll enjoy the hell out of this clip. [via io9]
