James Cameron has enlisted the help of celebrities in a new Showtime documentary series about climate change.

According to Indiewire, these celebrities include Matt Damon, Olivia Munn, and Arnold Schwarzenegger to name a few.

The series, titled Years of Living Dangerously, will premiere in April of 2014. Most documentaries use celebrity voices to narrate films. Showtime has gone one step further by using celebrity correspondents. These celebrities include Jessica Alba, Mark Bittman, Don Cheadle, America Ferrera, Harrison Ford, Thomas Friedman, Michael C. Hall, Chris Hayes, Dr. M. Sanjayan, Ian Somerhalder and Lesley Stahl.

The documentary will include the aftermath of Hurricane Sandy, Southwest droughts, public health issues of heat waves and firefighters battling what could be the worst fire seasons yet. The series will consist of six to eight one-hour long episodes.
