The Lost World: Jurassic Park (1997)

Plot hole: How did the men on the ship get killed? The bridge was intact and the T-Rex was still inside the cargo hold. [A raptor escapes from the boat when it pulls in to the harbour, but they cut the scene from the film and now that bit doesn't appear to make any sense.]

Other: When they're on the island and the INGen helicopters are flying in, Jeff Goldblum takes the binoculars and looks through the wrong end.

Factual error: When the vehicle is hanging off the cliff and the glass at the rear slowly begins to crack, it does so like sheet ice (or conventional window glass). Safety glass in vehicles would either be laminated (in which case it wouldn't shatter at all), or it would break into a million fragments...

Hammond doesn't appear in the second book (though he does in the second movie). This is because, in the book series, Hammond was killed in the first book. He slipped, broke his ankle and was fatally attacked by compys.

Several of the scenes from the first two movies are mixed from the books.

The T-Rex gets off the ship in San Diego. But the street seen is San Fernando Road in Burbank, about 130 miles north of San Diego.
