Movie is about a village and a monster.
There is a monster or creature outside of the village and all the inhabitants are afraid of it. A woman who is searching for her fiancé in Iceland comes upon the creature and the creature says that it was there when time began and remembers everything and that humans are a figment of his imagination and that he created humans to keep him company at the beginning of time because he was lonely.
He states that if he is killed humans cease to exist as well because we are from his mind. Eventually the villagers kill the creature. The screen fades to black and credits roll.
EDIT: I was just informed by my girlfriend that the movie was made in the late 90s or early 2000's and it is in fact a journalist looking for her husband in Iceland who encounters the creature and interviews him.
