I like these movies because you have to stretch to get your mind around them.
The Quiet Earth (1985, New Zealand) – Apocalyptic Change in Reality
The Earth goes through spasms changing time and location… interesting concept.
12 Monkeys (1995)-Time Travel & Apocalyptic Virus-director, Terry Gilliam– stars Bruce Willis
You might have heard of this but if not, worth seeing. Bruce is sent back in time repeatedly until he gets it right (reversing a virus outbreak). The time travel and portrayal of the past and post apocalyptic future is well done.
