 The film contains more than 2,200 visual effects shots completed by 14 companies: Industrial Light & Magic (ILM), Weta Digital, Scanline VFX, Hydraulx, Fuel VFX, Evil Eye Pictures, Luma Pictures, Cantina Creative, Trixter, Modus FX, Whiskytree, Digital Domain, The Third Floor and Method Design. ILM was the lead vendor and shared responsibility for creating many of the film's key effects, including the Helicarrier, the New York cityscape, digital body doubles, Iron Man and the Hulk. To create the on-screen Hulk, Ruffalo performed in a motion-capture suit on set with the other actors while four motion-capture HD cameras (two full body, two focused on his face) captured his face and body movements. Jeff White, ILM's visual effects supervisor, said, "We really wanted to utilize everything we 've developed the last 10 years and make it a pretty spectacular Hulk. One of the great design decisions was to incorporate Mark Ruffalo into the look of him. So, much of Hulk is based on Ruffalo and his performance, not only in motion capture and on set, but down to his eyes, his teeth, and his tongue."
