For those who aren’t working in the film industry, you probably didn’t know that Stan Winston Studio created multiple raptors for Jurassic Park, including several life-sized, cable-controlled puppets. However, some Raptor shots were most efficiently captured with a man in a suit.

SWS supervisor John Rosengrant was pegged as the main Raptor suit performer, with SWS concept designer Mark “Crash�” McCreery also pitching in when the shot required two raptors. For weeks prior to shooting his scenes, Rosengrant rehearsed in the suit, imitating the Raptor behaviors illustrated in Phil Tippett’s animatics. This Raptor performance was Rosengrant’s first major ‘acting’ role as a suit performer.
