The Ridley Scott-directed "Alien" prequel divided critics and audiences, and its impact is sure to be felt on Halloween. While some may get creative with the film's other characters (look for a few interpretations of Michael Fassbender's android character, or even the blood-splattered post-operation Noomi Rapace) , our bet is that many will aim to recreate the film's strange "Engineers." There are two options, as one can approximate them in their pale, extra-buff state (pictured) or wearing their elephantine space suits, as first glimpsed in1979's "Alien."
