The Quiet Earth
This film is nearly identical in plot minus some amazing science-fiction to that of The Quiet Earth (1985) based on the novel by Harrison of the same name (1981). For all intents and purposes, this film is a reboot.
Ironically, the original film is set in and made in New Zealand and arguably superior in every way as a post-apocalyptic thriller with some hard science-fiction on par with such films as Primer, Predestination, Coherence, etc.
