Trivia: Early in the film, an SUV is smashed by a wrecking ball in front of Whipstaff. A real SUV was smashed for that film and it was obviously one that had been in a wreck previously. Notice that the passenger door is crooked and pulled away from the frame.
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.
Trivia: When Karrigan and Dibbs are trying to get the ghosts out of the manor, they contact 'The GhostBusters'. Dan Aykroyd reprieved his role as Dr. Ray Stantz and fled from the building suggesting that they call someone else.
Answer: When Carrigan tosses the Whipstaff documents into the fireplace, one paper's hidden message appears on the back from the heat (if using lemon juice instead of ink, messages stay hidden and only appear when heated); it has a drawn map and handwritten "Buccaneers and buried gold, Whipstaff doth a treasure hold." Later, Casper tells Kat that he and his dad had great fun together playing pirates down in the lab, and Casper quotes the words from their hidden "pirate" message. So the handwritten note with map was actually part of their father/son beloved pirate-playing shared fun (note when the living Casper appears at Kat's party, he wears a piratey costume with a sword at his side). The pirate "treasure chest" contents were merely Casper's personal treasure: his glove and cherished autographed baseball, and it was kept in the lab's vault; even after Casper succumbed to pneumonia, Mr. McFadden kept it in the vault.
