Cinesite Provides 100 Effects Shots for Rush Hour 2
Cinesite uses a variety of proprietary tools to create its movie effects, including mooVRoto and mooVPaint
"The trick is to create the illusion that Jackie Chan and Chris Tucker survive imminent danger by doing heroic and breathtaking feats and making it totally believable," says Cinesite Visual Effects Supervisor Kevin Lingenfelser. "This sequence was all in Brett's [Ratner] mind. He storyboarded everything, though it constantly was evolving. We went through many variations and combinations. We just had to figure out how to do it."
The individual shots making up the finale are a combination of numerous 2D techniques and applications. Lingenfelser credits his effects team, including Digital Effects Supervisor David Lingenfelser, and a close collaboration with Ratner, 2nd unit director Conrad Palmisano, and cinematographer Matt Leonetti, ASC. The Slide For Life sequence was broken down into two types of shots. Wide shots of Chan and Tucker are digital paint removals of safety rigs and up to six cables. Close-ups of the stars are digital composites accomplished using a 40 by 60-foot digital bluescreen matched with background plates filmed in Las Vegas. Intricate split composites and bluescreens were used for the shots involving Chan and Tucker swinging over Las Vegas Boulevard. Foreground and bluescreen elements of them were filmed in both Los Angeles and Long Beach, California.
Backgrounds were then filmed in one night in Las Vegas using camera data from the foreground and bluescreen shoots. Another heavy effects shot, in the film's opening, involves a terrorist bombing of The American Consulate in Hong Kong. The shot starts with the camera high above an intersection and cranes down to follow the female villain (Ziyi) leaving the Consulate. She crosses the street and stops just as the third floor corner offices explode in a massive fireball, spewing multiple layers of glass, fire, debris and smoke out of the windows. The Consulate building was shot in Hong Kong without the benefit of an actual explosion. An air horn was used to provide the proper timing and stimulus for crowd response. Mike Joyce of Cinema Production Services built a 1/6-scale miniature of the top six floors of the Consulate. Pyrotechnics were designed and supervised by Ian O'Connor. The miniature, with pyro explosion, was filmed three separate times at 96fps to achieve the proper scale. The miniature element was then tracked to the original background plate, accounting for lens distortion. Elastic Reality was used to match and warp the miniature building's perspective to the live-action building.
Cinesite, which used SGI workstations to help create effects for Rush Hour 2, is moving to an Intel/AMD architecture running Linux.
Leonetti's first and second unit crews photographed all of the background plates in addition to the foreground and bluescreen elements featuring the actors and their stunt doubles. Lingenfelser notes that all of the effects elements were filmed in the same 35mm anamorphic format (2.4:1 aspect ratio) that Leonetti used for live-action camerawork. The only difference was that the bluescreen elements with Chan and Tucker were recorded on a slower, 200-speed Kodak Vision (5274) negative to reduce grain that would adversely affect proper matte extraction during the compositing process.
