When science fiction becomes reality: Experts reveal the most realistic APOCALPYSE movies - so, does your favourite blockbuster give us a glimpse at how the world will end?

From The Terminator to The Day After Tomorrow, movies have envisioned just about every possibility for how the world might end. If you're a science fiction movie buff, you might think that some of these apocalyptic scenarios seem a little far-fetched. But hold onto your popcorn, as experts say that some of these disastrous plotlines could actually become a reality. While we don't need to worry about an asteroid wiping us out like in Armageddon, experts warn that a bioweapon leak like 12 Monkeys could really end the world. And if your favourite blockbuster does give us a glimpse at how the world will end, not even Bruce Willis will be able to save us. Apocalypse movies find their inspiration in a number of different disasters, but which are the most realistic. An escaped bioweapon could pose a genuine threat of destroying humanity.
