Stupidity: When Dr. James Harvey dies, there should be a body left behind in the manhole. After Kat and Casper revive him in his ghost form in the Lazarus, he comes out with a body (and clothing). One can assume that there are now two bodies of him, one alive and one dead. That would make an interesting article in the newspapers of the next day.
Casper (1995)
1 stupidity
Directed by: Brad Silberling
Starring: Bill Pullman, Christina Ricci, Eric Idle, Cathy Moriarty, Chauncey Leopardi, Malachi Pearson, Spencer Vrooman
Continuity mistake: In the scene where Kat is being introduced to her new classmates, Casper is seen tying the students' shoelaces together. This includes the snobby blonde sitting in front. But when the camera pans out, her feet are clearly too far apart for this, not like how they showed them while being tied.
Kat: Drop dead.
Stretch: Too late.
Trivia: The interior of Whipstaff was built at Universal Studios. Early in production there were several moderate earthquakes in the Los Angeles area and many of the large cracks that appear on the walls, etc. were real.

Chosen answer: It was most likely Pneumonia, which was very deadly before the discovery of antibiotics.
