"The things [scientists] talk about sometimes don't resonate with the public," Schwarzenegger told reporters during the show's Television Critics Association panel. "There are very simple messages, but only actors will get the ultimate attention. This is why it's important when you're [famous] that you look at the power of communicating and use it for something positive."

Years of Living Dangerously, which is executive-produced by film veterans James CameronJerry Weintraub, climate change leader Daniel Abbasi and 60 MinutesJoel Bach and David Gelber, premieres April 13at 10/9c on Showtime. Check out our exclusive first look at the docu-series' key art below:
