1. Jurassic Park & REC — Monsters You Probably Assumed Were CGI:
Jurassic Park, released in 1993, was the biggest challenge. Spielberg had initially flirted with using go-motion for the dinosaurs but he was never entirely happy with the results, and asked for full-size animatronic robots. Work got under way to construct full-scale or near full-scale models of the film’s key dinosaurs. A moving, breathing T-rex; a steel-boned killing machine; a talking teddy. If Steven Spielberg or James Cameron could imagine it, effects genius Stan Winston could build it. A 9,000lb Tyrannosaur that could be controlled and adjusted live on set, as well as the velociraptors, dilophosaurus and the sick triceratops that was shot on the very first day of filming.
