Industrial Light & Magic, a division of Lucasfilm Ltd. and now owned by The Walt Disney Company, forever changed the way movies are made and how we as the viewer experience them. The movie-making geniuses have continually raised the bar in computer-generated imagery (CGI) and visual effects (VFX) year after year since the company’s founding by George Lucas in May of 1975. Released today, ILM takes us behind the scenes to show us how they used laser scanning and other tools to transform Mark Ruffalo into the lovable Hulk character that almost stole the show in Marvel’s third highest-grossing film of all time, The Avengers.
