David Letterman has signed on to join 10 other celebrities doing episodes for the climate change docu-series "Years of Living Dangerously," making the Emmy Award-winning show his first venture after his "Late Night" television stint.
Letterman was approached by "Years of Living Dangerously" producers Joel Bach and David Gelber about his availability after watching the talk show host interview scientists on the issue,
according to The Hollywood Reporter.
"It's thrilling to have him do this — we're beyond excited," said Bach. "The reason why Letterman's part of this is that we just noticed that he seemed to perk up when this issue came across his lap. We reached out to him to see if he'd want to be part of this, and he said, 'Absolutely.' He said [that climate change is] something he does think about a lot."
Variety said Letterman will join other celebrities who agreed to host episodes on the National Geographic channel series, including Jack Black, Ty Burrell, James Cameron, Thomas Friedman, Joshua Jackson , Aasif Mandvi, Olivia Munn, Arnold Schwarzenegger, Ian Somerhalder and Cecily Strong.
Bach said he wasn't surprised by Letterman's interest in the series.
"You could just tell. Whenever they would have a climate discussion, he would really kind of perk up," said Bach. "And it turns out he does, he cares about it a lot. He's definitely invested in this issue."
National Geographic Channels chief executive Courteney Monroe told THR that Letterman's involvement points to what she believed to be a strong public interest in the subject.
"(Letterman's involvement) speaks to how passionate so many people are — like himself — about this issue and how important it is to our planet and to humankind, and I think it's terrific that he's attaching himself to it," said Monroe.
"What's interesting and important is this is not a political issue at all, but it's an incredibly important issue that affects all of us as people living on this planet, and I think that's why they're able to attract the names that they've attracted," she added.
The National Geographic Channel will debut the second season of "Years of Living Dangerously in the fall of 2016.
