8 Sci-Fi Movies Built On A Lie

8. Waterworld

Waterworld has a special place in cinema history, with it often lambasted as one of Hollywood's most problematic pictures.

An idea initially conceived in 1986 from screenwriter Peter Rader, the film would officially be in some form of loose development from 1989 before it was finally released in 1995. But while the film did eventually swim its way to the silver screen, the initial budget of $100 million was blown out of the water when the movie ended up costing a reported $175 million to make.

That's enough about the production of the picture though, for there's one massive lie holding Waterworld together.

Set in the year 2500, Waterworld takes place at a time when sea levels have risen to over 25,000 feet, which in turn has sunk every single of the planet's continents and meant that the only way for humans to survive is to live in floating communities.

Putting a science cap on, and the whole premise of Waterworld just isn't at all possible.

Sure, there's always room for some liberties to be taken in sci-fi films, but there simply is not enough water in the Earth's atmosphere to make it possible for Waterworld's dystopian landscape to come to pass. Even if all of the ice caps melted, that would flood coastlines but leave any inland areas completely untouched.
