The Relic

Because the novel portrayed the museum's administration in an unflattering light, they turned the film's producers down. Paramount Pictures offered the museum a seven-figure sum of money to film there, but the administration was worried that the monster movie would scare kids away from the museum. The producers were faced with a problem as only museums in Chicago and Washington, D.C., resembled the one in New York. The Field Museum of Natural History in Chicago loved the premise and allowed them to shoot there.

In the book by Douglas Preston and Lincoln Child, the monster has been in the museum's subbasement for around seven years, making the lair filled with either partially or fully decomposed skeletons completely plausible. However, in the movie they change the duration to only six weeks. The lair they find in the movie with tons of skeletons doesn't connect with the time it took for them to become that decomposed.
