- Alien (rogerebert.com)
At its most fundamental level, “Alien” is a movie about things that can jump out of the dark and kill you. It shares a kinship with the shark in “Jaws,” Michael Myers in “Halloween,” and assorted spiders, snakes, tarantulas and stalkers. Its most obvious influence is Howard Hawks’ “The Thing” (1951), which was also about a team in an isolated outpost who discover a long-dormant alien, bring it inside, and are picked off one by one as it haunts the corridors. Look at that movie, and you see “Alien” in embryo.

The halogens (/ˈhælədʒən, ˈheɪ-, -loʊ-, -ˌdʒɛn/) are a group in the periodic table consisting of six chemically related elements: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and the radioactive elements astatine (At) and tennessine (Ts), though some authors would exclude tennessine as its chemistry is unknown and is theoretically expected to be more like that of gallium. In the modern IUPAC nomenclature, this group is known as group 17.
