WATCH: Leonardo DiCaprio Surprises Fans on ‘Ellen’ to Promote His New Documentary ‘Before the Flood’

Few things will likely inspire Leonardo DiCaprio to do unscheduled press, but promoting his new documentary Before the Flood is definitely one of them. On the spur of the moment, the Hollywood heartthrob dropped by Ellen DeGeneres’ daytime talk show today (Nov. 4, 2016), sending the studio audience members into a frenzy.

After speaking with Justin Timberlake and Gabrielle Union (which is a damn good episode in its own right), DeGeneres made a point to encourage those in attendance to check out DiCaprio’s new documentary about the climate crisis and its devastating effects all over the world. But she didn’t have to make the case on her own; that’s when she invited out the Revenant star.

After the cascades of screaming died down, DiCaprio explained just how near and dear his new film is to him.

“This was a three-year endeavor on behalf of Fisher Stevens, the director, and myself. We literally traveled all around the world from Greenland to Indonesia, we got to speak to some incredible world leaders, some fantastic scientists, we got President Barack Obama in the documentary, we have the Pope in the documentary. We’re basically trying to convey the science of the climate change to the general public,” DiCaprio explained. “This is happening faster than anyone could have predicted. It’s a very urgent issue.”

The leading man also encouraged viewers to get out and vote in this upcoming election, noting that whoever is elected president could play a serious role in how we manage climate change in the years ahead.

“2016 was the hottest year in recorded history. July was the hottest month in recorded history. We want people to keep that mind when they go to the polls,” he said. “We need leaders that want to take action on this issue, that believe in modern science. So go out there this November 8th, please vote.”
