Aliens are invading
In Edge of Tomorrow (2014), the film is set in 2020 and most of Europe has been invaded by an alien race called Mimics. They arrived via asteroid in Germany in 2015 and quickly conquered most of the continent. When the film joins the situation in 2020, a global defence force has finally enjoyed a localised victory thanks to new powerful exoskeletons. Tom Cruise as Major William Cage finds himself in the midst of this, finding himself in a loop of battles with the Mimics and then waking up at Heathrow Airport – now a military base.
Humanoid robots
In the film I, Robot (2004) starring Will Smith, the company that created humanoid robots to serve humanity was founded in 2020.
We discover the Martians created us
Mission to Mars (2000) is a film that sees astronauts in 2020 embark on the first ever mission to Mars. Instead of finding that the planet is habitable, the astronauts discover that Mars was previously hit by an asteroid that caused the natives of Mars to evacuate. The Martians left in spacecrafts, but sent one of these crafts to Earth with DNA to create humans – who would later have the capability of landing on Mars. As humans are recognised as being descendants of Martians, one astronaut is invited to continue his journey to meet the former Mars natives in their new home planet.
