 According to Winston, "He felt neither of [the drafts] balanced the science and adventure elements effectively ... too much science will make the movie too talky, but too much adventure will make it seem hollow".Progress on the film stalled during 2005 as Marshall and Spielberg were busy with other film projects.At the end of the year, Spielberg said he planned to include a scene inspired by Crichton's novel "The Lost World" that would involve characters on motorcycles as they flee from raptors.
