The 1989 underwater creature feature Leviathan, directed by George P. Cosmatos, is a classic example of a movie that has become a cult classic. The movie follows the crew of a deep-sea mining rig as they encounter an unknown creature lurking in the depths of the ocean. Although the creature design may have been more to be desired, what makes this movie stand out are its great one-liners and intense action sequences. The film also features some great visual effects and memorable performances from Peter Weller and Ernie Hudson.
