* 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.
* HeyItsThatGuy: Film/LawrenceOfArabia runs a hotel, and the guests include [[Film/PoliceAcademy Carey Mahoney]], [[Film/NationalLampoonsVacation Ellen Griswold]], that guy from ''Film/SexLiesAndVideotape'' and the Film/BrideOfChucky (or, if you prefer, the voice of [[WesternAnimation/FamilyGuy Bonnie Swanson]]). Not only that, two of the ghosts are [[Film/{{Splash}} the mermaid from Splash]] (or Elle Driver from ''Film/KillBill'' to younger viewers) and [[Film/ThePhantomMenace Qui-Gon Jinn]]. Slightly less recognizable is Connie Booth, most recognized as many of the female characters on ''[[Creator/MontyPython Monty Python's Flying Circus]]'' and Polly Sherman on ''Series/FawltyTowers''.
