Creating the Hulk in CGI was one of the most complex tasks Industrial Light & Magic had ever undertaken at that time. The computer model used 12996 texture maps, and required 1165 muscle movements and 100 layers of skin. It took the combined work and efforts of about 180 ILM technicians (69 technical artists, 41 animators, 35 compositors, 10 muscle action animators, 9 CG modellers, 8 supervisors, 6 skin painters and 5 motion-capture wranglers), over 2.5 million hours and one and a half years for him to be effectively created and portrayed in the film. With all that work, some of the public complained that the Hulk looked too fake, comparing him with Shrek (2001).
Filming of Hulk constituted hiring 3,000 local workers, generating over $10 million into Los Angels' local economy.
