I remember watching this movie when I was just a little kid.  It was in the early 80s when I remember watching it.  I thought it was a old star wars movie but when asking a friend who is a star wars nut, he couldnt remember the scene.  But the scene that I remember, there was a man walking through a forest on his way to save, I think, his father and mother, and this huge harry dog like creature gets after him and he hides in a trunk of a tree to escape and the harry monster tries to get to him inside the tree.  And then something distracts the monster and he is able to leave the tree and continue on to save his parents or whoever he was trying to save.  I know all this sounds weird but I do remember the movie and I have been trying to find this movie all over the place.  If someone could please help me that would be awsome!

Thanks.
