Watch the first full trailer for "Terminator: Genisys"

The first trailer for "Terminator: Genisys" is here, and it's definitely cause for excitement.

The film brings the return of Arnold Schwarzenegger, along with "Game of Thrones" actress Emilia Clarke, Jason Clarke, Jai Courtney, Matt Smith and J.K. Simmons.

The plot centers around Kyle Reese, who offers to go back in time to protect John's mother, Sarah Conner, from Terminators. But apparently when he gets there, "everything's changed."

Could've fooled us; the trailer offers some familiar catchphrases, a T-1000 -- and actually seems very similar to the original. Not that we're complaining -- looks like fun!

"Terminator: Genisys" is the fifth film in the "Terminator" franchise and is due out in July 2015. For now, check out the trailer below:
