Casper (film)/WMG

Casper (from the early 1990s movie) is Charles Foster Kane.
The poor, rural background of Kane's family is a cover. The "hick" father is actually a loving Mad Scientist. The reason Kane's mother wants to send him away is that she doesn't approve of her husband's experiments, and dosen't want to her son to get into them. The father, depressed and enraged, plunges into his work...

According to some paranormal researchers (or so I've heard), people's spirits can leave (again, this is a movie, so screw physics I have plot), residual energy behind. Kane's father became obsessed with harnassing this energy that Kane would have left at his home with Rosebud. It works (somewhat) creating Casper, the friendly ghost and essence of Charles Foster Kane's happiness.

Anyway, i think this is what I heard paranormal researchers believe (though I don't myself). If anyone knows anything else about this, feel free to fix any mistakes in understanding I have shown.
 * Kane's parents lived in Colorado, Xanadu is in Florida and Whipstaff Manor is in Maine. That looks like a bit of a geography problem.

Ray had a good reason to bail on the job.
It was one against three. Furthermore, wrangling ghosts with a proton stream and throwing a trap is probably a pretty hard job for just one person. Still, it was kind of stupid for him to go in alone.

The Ghostly Trio are another reason Casper's father invented the resurrector
Think about it - John McFadden's brothers all die violent and/or painful deaths. Then Casper dies of peunomia. No wonder McFadden wanted to make a machine to bring people back from the dead. I couldn't help but wonder what their unfinished business was. Casper's was looking after his dad.
 * Maybe their unfinished business was looking after Casper and his dad? They seemed to have a soft spot for Casper. If they were close, they might have stuck around to watch over Casper while his dad was likely depressed over their deaths.
 * How do we know that they're not Casper's mom's brothers?
