Enlisting the help of a celebrity narrator is a tried and true way for issue docs to try to get an extra boost of attention. Showtime is going one step further with "Years of Living Dangerously," an upcoming doc series slated for April 2014 that will bring in a slew of famous faces to serve as correspondents traveling the globe for an in-depth examination of climate change.

The series, which will run six to eight hour-long episodes, also comes from some big names -- James Cameron, Jerry Weintraub and Arnold Schwarzenegger are the executive producers, alongside Joel Bach and David Gelber ("60 Minutes") as well as climate expert Daniel Abbasi.

The correspondents are Jessica Alba, Mark Bittman, Don Cheadle, Matt Damon, America Ferrera, Harrison Ford, Thomas Friedman, Michael C. Hall, Chris Hayes, Olivia Munn, Dr. M. Sanjayan, Arnold Schwarzenegger, Ian Somerhalder and Lesley Stahl. The topics they'll tackle include the aftermath of Super Storm Sandy, severe droughts in the Southwest, the public health impact of heat waves and elite firefighters facing what could be one of the worst fire seasons yet. Check out the trailer below -- is that enough star power to bring new attention to the issue?
