Leterrier cited Andy Serkis' motion capture portrayals of Gollum and King Kong in "The Lord of the Rings" and "King Kong", respectively, as the standard he was aiming for. Norton and Roth filmed 2500 takes of different movements the monsters would make (such as the Hulk's "thunder claps"). Phosphorescent face paint applied to the actors' faces and strobe lighting would help record the most subtle mannerisms into the computer. Others including Cyril Raffaelli provided motion capture for stunts and fights, after the main actors had done video referencing. Leterrier hired Rhythm and Hues to provide the CGI, rather than Industrial Light &amp; Magic who created the visual effects for Ang Lee's "Hulk". Visual effects company, Image Engine, spent over a year working on a shot where Banner's gamma-irradiated blood falls through three factory floors into a bottle. Overall 700 effects shots were created. Motion capture aided in placing and timing of movements, but overall key frame animation by Rhythm and Hues provided the necessary "finesse [and] superhero quality". Many of the animators and Leterrier himself provided video reference for the climactic fight.
