Here's why:
* Keanu Reeves plays Ted Logan in the movie.
* A devil named "The Devil" (played by William Sadler) comes out to get Ted and Bill.
* Goblins are used as a method to control and manipulate people in the movie.
* The devil tries to marry a woman (a very different woman than the one Ted is in love with) and use that as a means to obtain power.
Let me know if you have any other movie questions!
