KMC Forums - What's the name of this movie?

Hi, I'm trying to remember the name of this movie I saw a long time ago.
I will try to write everything I remember. To point out its before 2000 and I can't remember if it was an American movie or not.

An old big house near a graveyard in a farm or a forest. The beginning is an old man with white hair following the camera and a monster knocking on the house front door the monster has long fingernails. The old man goes down the stairs and looked at his wife's picture. The monster was making a wired voice. The old man looked through a hole in the door to see the monster face. It eyes were yellowish green and really big teeth. The monster has some kind of an animal legs. The old man opened the door, he saw the monster and was shocked. The monster grabbed him by his jaw and by his hand he ripped the old mans heart.

That's all I remember. Thanks all
