There is a young boy. I think he is blonde. If I remember correctly he gets stuck a strange world with strange/scary creatures. Also in the film there is an old bald man. He has a patch on his head covering a wound/scar. I think it's the boy who has grown up into the old man. The scar on his head is from whatever happened to him as a boy. Any ideas what the film is? My sister and I have been pulling our hair out.
