Velociraptor was popularized by its appearance in the Jurassic Park franchise, which features numerous individuals. They first appear in Michael Crichton's 1990 novel Jurassic Park, followed by a 1993 film adaptation from director Steven Spielberg, which spawned a series of films. Despite their name, Crichton heavily based the Velociraptors on the larger Deinonychus, and this was carried over into the films. The on-screen raptors were created using several production methods, including animatronics by Stan Winston and CGI by Industrial Light & Magic (ILM).
