An hour sit down between Leonardo DiCaprio and President Obama was so academic it only managed to one truly titillating moment, but it's a beautiful one. At the climate discussion between the president, the actor, and climate scientist Dr. Katharine Hayhoe as part of SXSL (South by South Lawn), DiCaprio admitted he signed up for a trip to Mars.

Hayhoe: The reality is, if we're a human living on this planet, which most of us are, as long as we haven't signed up for the trip to Mars—I don't want to know if anybody has, I think you're crazy.


At this point, DiCaprio shrugs, takes a sip of water, and drops a casual, almost resentful, "I did."

"Oh, you did?" asks Hayhoe, and DiCaprio confirms with another ambivalent shrug and nod, apparently referring to the 2015 application for Mars One or Elon Musk's recent Mars announcement.

Hayhoe starts to laugh and apologize when Obama cuts in to say, "No no, he is—I think he'll acknowledge he's crazy. That's okay. He's fine with it."

Watch the moment at around the 37 minute mark.
