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: It was not Casper (now a ghost of 12 yr old boy) who wrote there was a hidden treasure at Whipstaff Manor. It was Casper's father, Mr. Mcfadden. The treasure in the box is an autographed baseball which used to belong to Casper, before he got sick and died. Mr. McFadden missed his young son Casper, so he invented a machine that can bring a ghost back to life. He considered Casper's baseball a treasure, because to him it is the greatest treasure there is - the baseball that belonged to his 12 yr old son before he died.
