Jurassic Park's continuity runs deeper than most players realize. Sarah Harding, the paleontologist played by Julianne Moore in The Lost World: Jurassic Park (1997), is the daughter of Gerry Harding, the veterinarian from Steven Spielberg's original Jurassic Park (1993). Gerry, portrayed by Bob Peck, appears briefly in the first film to treat the sick Triceratops and later dies during the Tyrannosaurus attack.
This family connection never appears explicitly in either film's dialogue. The films offer no mention of their relationship, no flashback, no exposition dump. Instead, screenwriter David Koepp wove the detail into the script's background without drawing attention to it. Fans discussing the franchise for decades largely missed this detail, which makes Polygon's revelation feel genuinely surprising for long-time viewers.
The connection adds thematic weight to The Lost World's narrative. Sarah arrives at Isla Sorna as part of a research expedition, motivated partly by her scientific passion but also carrying familial weight that most viewers never consciously recognized. Her father's experience on Isla Nublar during the original disaster adds unspoken context to her decisions on the darker, more dangerous Site B.
This type of hidden continuity reflects how The Lost World operates as a direct sequel rather than a soft reboot. Director Steven Spielberg returned to helm the follow-up, maintaining tonal and narrative consistency despite introducing new locations and primarily new characters. The franchise later moved away from this approach, with Jurassic Park III, the Jurassic World trilogy, and upcoming projects often treating earlier installments as distant history rather than closely interconnected events.
The reveal demonstrates how even widely discussed franchises contain layers that escape mainstream attention. Jurassic Park remains culturally dominant enough that
