He could be talking about 13 Ghosts. The original film from the 1960s.
That movie was about a mid-west town in which you could only spot the bad guys with special glasses.
What is it with Special Glasses? Moroni would be proud.
[i]A family finds out they’ve inherited a large estate from their uncle. But this somewhat zany man was a ghost collector, and without their leader, the ghosts are running a bit wild. The head of the family is a professor, and discovers a strange pair of glasses that he thinks will enable him to see ghosts. His son thinks all things ghostlike. Meanwhle, mom is warding off pot-throwing poltergeists, and sis has a run-in with the Ouija board. Will they get through this house alive?[/i]
Don’t think this is it tho either. Hrmmm
