Is the “Extra” in Extra Terrestrial similar to the “Extra” in Extra Strength Tylenol? Like, there is there a Regular Terrestrial (R.T.), or even a Maximum Terrestrial (M.T.)? Anyway, 1982’s blockbuster cultivated a whopping $792,910,554 in worldwide box office sales during its tenure in theaters, which calculates to $1,940,116,550.26 with inflation (source: http://www.usinflationcalculator.com/). But don’t worry your pretty little sky-searching head, because this epic film’s original motion picture soundtrack can be had at a fraction of a fraction of a fraction (of a fraction) of the price. $2.73 over at Discogs, and this essential otherworldly soundtrack can be yours.
