Beetlejuice (1988) directed by Tim Burton is a fantasy-comedy film about a married couple who go through a car accident and find themselves dead, spirits trapped in their own home trying to get used to the afterlife.
As a new family moves into their home, a being called "Beetlejuice" promotes himself to them as the "Bio-Exorcist".
The Beetlejuice Website project welcomes you, the recently deceased, to the afterlife.
Just be careful not to release Beetlejuice!
