It is not an overstatement to say Alien is a masterpiece. Ridley Scott’s seminal sci fi horror film is a work of art and it owes a great deal to it’s titular creature designed by H.R. Giger. It is without a doubt in my opinion the greatest movie monster ever created. We have seen plenty of movies with aliens, yet none feel quite as frightening, fully realized and extraterrestrial as the Xenomorph. It has been 36 years since the original Alien film was released and no creature seen since (aside from it’s buddy the Predator) has had the cultural impact or longevity as Giger’s creation.
