They Live’s John Nada (Roddy Piper) carried a heavy burden once he discovered that box of sunglasses down at the old church. He can’t unsee the horrible reality those shades reveal; as the old saying goes, “Once you see aliens in white and black, you never go back.” Even more than the cluster headaches, Nada’s biggest challenge was undoubtedly trying to get Frank Armitage (Keith David) to put on the glasses and see the world as Nada does. Only the glasses can set Frank free, but he resists, and what unfolds is arguably the greatest, most unnecessarily protracted fight scene in film history. Set in an alleyway filled with hazardous props, these two lumbering titans square off, each landing strikes in a leather-slapping triumph of foley work.
