If you had to think of two of the biggest science fiction franchises to have ever hit the big screen, we'd understand if you included ones that involve phasers and force-wielders. There were 11 years between "Star Trek" making its television debut and George Lucas introducing us to a universe of droids and Jawas in 1977. In 1979, Starfleet made it onto the big screen in "Star Trek: The Motion Picture," followed by a series of highs and lows. With that, we've gathered up what we consider to be the best movie sci-fi franchises that aren't "Star Wars" or "Star Trek." So while you wait for the dilithium crystals to get fired up on the Enterprise or for Han to jump to hyperdrive, check out our rankings of the best sci-fi movie franchises that go beyond both, starting with a franchise that houses a pair of the most successful films ever made.
