Charlie's Ghost Story (1995)

Charlie's archeologist father has recently found the bones of the conquistador Coronado, and his discovery is taking up so much of his time that he seems to be forgetting about his son. One night, visiting the local museum, Charlie (Trenton Knight) bumps into Coronado's ghost (Cheech Marin) and agrees to help him get his bones reburied. Coronado might be a crazy old ghost, desperate for a little bit of eternal rest, but maybe, just maybe, he can bring Charlie and his father back together again.
