So, I always found 57 years gap between events of Alien and Aliens to be weird. Why 57 years ? Why not 50, why not 100 ? It's usually a rounded number in movies, so why 57 years ?
And suddenly I remembered something: Alien takes place in 2122, 2122 plus 57 equals 2179, right ? 2179, huh ? Can it be a slight nod towards original movie's release year - 1979 ?
