10 Best Multiverse Movies Ever
8. Star Trek (2009)
J.J. Abrams made extremely clever use of the multiverse in his 2009 Star Trek reboot.
While most fans pre-release expected Abrams to give the flagging IP a full reboot, he ingeniously decided to set the movie in a parallel universe to the "Prime" Star Trek universe, meaning that the adventures of the Enterprise's original crew still happened within this continuity.
Better still, Abrams managed to have his cake and eat it too by having Spock Prime (Leonard Nimoy) end up in the alternate universe (known as the Kelvin timeline) and help the alternate Captain Kirk (Chris Pine) vanquish the villainous Nero (Eric Bana).
By getting Spock Prime to interact with the new Enterprise cast - and even Spock's own younger self (Zachary Quinto) - Trek '09 delivered giddy fan service in a clever and at-the-time wildly original way.
That the multiverse aspect actually felt like an organic part of the story - the Kelvin timeline having been created by Nero after he traveled through a black hole and destroyed the USS Kelvin, thereby changing history - was just the icing on the cake.
