* ExecutiveMeddling: Jordan, who wrote and directed the film, intended it to be more serious. There was more scenes with Liam Neeson, and the ghosts were more involved in the plot, but the studio had no idea how to market it and recut it against Jordan's wishes. A shorter version of this cut was released in Japan.
* FakeIrish: Daryl Hannah, complete with terrible accent. Peter O'Toole doesn't even try. The rest of the Irish cast are actually Irish actors, though.
