Did marketing for Terminator Genisys give away too much?

When the second trailer for Terminator Genisys hit, the Internet ran amok over the marketing spoiler that the beloved leader of the resistance, John Connor, was no longer just man, but an evolved and presumably evil cyborg-esque character.

But the man behind John Connor, 45-year-old Australian actor Jason Clarke, says there’s much more to the story than meets the eye.

“To reveal something that big, there’s obviously still a lot more there. There’s a lot more going on,” Clarke told ETonline. “It's always a funny thing about how much you give away and how much you don't give away and what makes people interested in general. [It] shows that you're doing something that stands on its own two feet.”

Clarke stars opposite Emilia Clarke (Sarah Connor), Jai Courtney (Kyle Reese), and Arnold Schwarzenegger… because what’s a Terminator film without Arnold?

“He’s a fascinating man and he made this character,” said Clarke. “[Arnold] and James Cameron made a machine, that slaughters everyone in the first film, interesting and loveable and warm and funny and a hero.”

Clarke has been thrust into the spotlight in recent years. Though his career has spanned decades, he’s recently landed major roles in several high-profile films including Zero Dark Thirty and Dawn of the Planet of the Apes.

The next Apes film, War of the Planet of the Apes, is set to hit theaters in July 2017 – we asked Clarke about his possible involvement in this video.
