How many mattes are there in Robocop?
RoboCop contains seven matte effects painted mainly by Gioffre. Each matte was painted on masonite. Gioffre supervised on-site filming to mask the camera where the matte is inserted. He recounted having to crawl out from a 5-story high ledge to get the right shot of the Plaza of the Americas. The burnished steel RoboCop logo was developed using special photographic effects that supervisor Peter Kuran based on a black and white sketch from Orion. Kuran created a scaled-up matte version and backlit it. A second pass was made with a sheet of aluminum behind it to create reflective detail. RoboCop's vision was created using hundreds of ink lines on acetate composited over existing footage. Several attempts had to be made to get the line thickness right; at first, the lines would appear too thick or too thin. Assuming thermographic photography would be expensive, Kuran replicated thermal vision using actors in body stockings painted with thermal colors and filmed the scene with a polarized lens filter. The OCP boardroom model of Delta City was made under the supervision of art director Gayle Simon.
