Another more complicated variation on stop motion is go motion, co-developed by Phil Tippett and first used on the films The Empire Strikes Back (1980), Dragonslayer (1981), and the RoboCop films. Go motion involved programming a computer to move parts of a model slightly during each exposure of each frame of film, combined with traditional hand manipulation of the model in between frames, to produce a more realistic motion blurring effect. Tippett also used the process extensively in his 1984 short film Prehistoric Beast, a 10 minutes long sequence depicting a herbivorous dinosaur (Monoclonius), being chased by a carnivorous one (Tyrannosaurus). With new footage Prehistoric Beast became Dinosaur! in 1985, a full-length dinosaurs documentary hosted by Christopher Reeve. Those Phil Tippett's go motion tests acted as motion models for his first photo-realistic use of computers to depict dinosaurs in Jurassic Park in 1993. A low-tech, manual version of this blurring technique was originally pioneered by Władysław Starewicz in the silent era, and was used in his feature film The Tale of the Fox (1931).
