Jurassic Park will forever be a classic. The people that put in all the hard work were doing things that had never been done before. One of which was to make a velociraptor move. Stan Winston Studio created a full raptor suit for SWS supervisor John Rosengrant to essentially wear in the film.
To determine how the suit should fit, the Winston team overlaid Raptor drawings on images of Rosengrant in various positions. The crew then did a body cast on him, and sculpted the Raptor form around that cast. Rosengrant then practiced for weeks on how to mimic the movements correctly. This is phenomenal.?
