The Quiet Earth (1985)
I want to thank u/leaves72 for including this film in one of our weekly viewing assignments. I had never heard of this New Zealand film, but I am still overwhelmed by the quantity and quality of comments my review received here, and on r/iwatchedanoldmovie. I heard from fans who saw it new in the theater, or on a VCR; from those who maybe stumbled on it like I did (it was not the sub's selection that week, so I apologized for being obstreperous). They shared their profound appreciation for this tidy little flick, and I am humbled that I stumbled on it through no agency of my own. Thank you, u/leaves72.
