Brad Pitt did some heavy soul-searching for his recent profile in GQ Style. But on Tuesday’s episode of The Late Show, the actor turned his lens outward, preferring instead to focus on questions about the universe writ large.

For the sketch called “Big Questions with Even Bigger Stars,” Pitt lay next to Stephen Colbert and got deep in a way that only two bros lying on a blanket under a starry night can.

“If the universe includes all of existence, what existed before the universe,” Pitt asks Colbert. “Probably a teaser trailer for the universe with, like, one really good scene that isn’t even in the universe when it’s released,” Colbert responds.

At one point, Colbert called Pitt a “solid eight” out of 10 in the looks department, to which Pitt responded "You’re sweet. Thanks, thanks.” Colbert wasn’t nearly as kind to one of his favorite targets, Sean Spicer. “An endless void. No answers. No meaning. No way to construct coherence from the swirling chaos,“ Colbert said about the heavens above, before revealing that he was actually looking at a cloud shaped like the embattled White House press secretary.

Of course, Pitt wasn’t just there for an existential meditation on the meaning of life. He was there to promote his upcoming military romp War Machine, a plug both men managed to fit in with aplomb. “Would you rather time travel to the past or the future?” Pitt asks Colbert to close out the bit. Colbert revealed that he’d travel to the future, not with the goal of learning about new technologies to help save all of the world’s problems, but so that he doesn’t have to wait until May 26 to watch Pitt’s latest movie on Netflix.
