Short doc includes Hillary Clinton, Sigourney Weaver, Jack Black, America Ferrera, and more

Instead of premiering his next film in theaters, James Cameron is headed to the Democratic National Convention.

Cameron and Maria Wilhelm have produced a short film titled Not Reality TV, which will premiere Wednesday at the DNC to draw attention to global warming. Sigourney Weaver, who narrates the film, will introduce the short at the convention and speak about the effects of climate change.

“We made this film to show the reality of climate change — how it’s directly affecting millions of people each day,” Cameron said in a statement. “America just experienced its hottest year ever, rapidly rising sea levels are threatening coastal communities and causing migrations across the globe, and extreme weather events like wildfires and hurricanes continue to spiral out of control as temperatures rise. As I’ve said before, to save our planet we need to mobilize like we did during World War II — the threat to our country and children is that severe.”

Celebrities like Jack Black, Don Cheadle, and America Ferrera appear in Not Reality TV, as well as politicians like Hillary Clinton, former California Gov. Arnold Schwarzenegger, New York Gov. Andrew Cuomo, and Washington Gov. Jay Inslee, speaking out about climate change and outlining specific policy plans to combat the issue.
