The Visitor (1979)

John Huston stars as an intergalactic warrior who joins a cosmic Christ figure in battle against a demonic 8-year-old girl and her pet hawk, while the fate of the universe hangs in the balance.

Multi-dimensional warfare, pre-adolescent profanity, and brutal avian attacks combine to transport viewers to a state unlike anything they've experienced somewhere between Hell and the darkest reaches of outer space.
