Back in the mid-1980s movie goers hadn't yet grown instantly skeptical of an impending sequel. There had been more than a few sequels by this point in time but the idea that they tended to end up as shameless cash-ins where the studios simply repeated what had come before - adhering to the false notion of "it if ain't broke don't fix it" - was yet to become a noticeable trait in popular culture. That said, the news of a sequel to Ridley Scott's seminal horror-science fiction classic Alien made more than a few people nervous that the end result wouldn't stand a chance of living up to the original. Scott's movie had all but revolutionised the genre, delivering tension and shocks amidst a setting which oozed atmospheric production design just as the alien in question oozed acidic blood. Fortunately, James Cameron was mindful from the beginning to avoid simply repeating what Scott had done, while the tag line "This Time It's War" made it clear that this wasn't going to be a straight rehash but something entirely different. Indeed, Aliens is hands down one of the greatest sequels of all time, delivering a punchy, pacy sci-fi action movie unlike anything else seen at the time. As with so many great movies, the little touches and behind the scenes anecdotes really bring the legend to life. Here are ten awesome facts about Aliens you probably didn't know.
