In space, no one can hear you scream never sounded so good, if one is a fan of 1979s Alien. Director Ridley Scotts classic sci-fi horror film is currently celebrating its 45th anniversary with a special rerelease in movie theaters. Plus, adding insult to injury, Alien is actually outpacing and outperforming Bill Skarsgrds new movie, Boy Kills World, at the box office.
