The one creature in the universe that could discourage me from being an astronaut is strangely enough one of my favorite horror creatures. The Xenomorph or Alien was first introduced in the 1979 film of the same name, and although the film came out before my time, it stills bring in the scares. The concept of Alien was brought forward by Dan O’Bannon and Ronald Shusett, who wrote the script for the 1979 film. However the Xenomorphs design was the brain child of H. R. Giger. The creature is truly alien in the way it looks, sounds and even evolves (I’ll discuss that later on). The Xenomorph has been in a grand total of seven films over its impressive lifetime, and although not all the films were perfect, the majority were some of the best Sci-Fi/Horror films ever made.
