How the cast of Jurassic Park should really look
Michael Crichton's Jurassic Park novel was arguably the high point of his career as a writer, but director Steven Spielberg and screenwriter David Koepp obviously made some changes to the novel's story when they adapted it for the big screen. The filmmakers took some liberties with the appearances of the book's human players, but the most dramatic departures relate to the dinosaur "cast."
First, let's cover the film's hero, paleontologist Dr. Alan Grant. We've done some Photoshop work in the above image to visually show you how he might have appeared if Sam Neill's look was more closely in line with the way the character is described. Most notably, in the book Alan Grant sports a beard and is barrel-chested. This is likely because renowned paleontologists Bob Bakker and Jack Horner—both facial hair aficionados—were Crichton's inspiration for the character. A picture of either of these men from the 1980s is a closer approximation to how Crichton meant Grant to look. Also worth noting is that, in the book, Grant is fond of children. The movie version of Grant is irritated by John Hammond's grandchildren, but eventually warms up to them. Another difference: Grant is a single widower in the novel, but has a relationship with Ellie Sattler (Laura Dern) in the movie.
