The publicity trail can take some strange detours, as Jennifer Lawrence and Chris Pratt found out when they stopped by the BBC Radio 1 studios in London to promote their upcoming sci-fi film, Passengers. There, host Scott Mills persuaded them to participate in a game called “Playground Insults.” The rules are simple: The players sit, facing each other, attempting to maintain eye contact while exchanging childish taunts. “The game ends,” Mills says, “when someone absolutely loses it or makes the killer insult.” The point is to make the other person laugh, Mills emphasizes, not to wound an opponent with words. Even so, Pratt seems to have an unfair advantage, as Lawrence cannot keep a straight face even when the rules of the game are being read aloud. She’s never more than a few seconds away from laughing.

Pratt and Lawrence genuinely seem to like each other (“I can’t think of anything bad about you,” Pratt admits at one point), yet neither is above taking a few good-natured potshots at the other’s career. “Why did they call it Joy?” Pratt asks. Lawrence responds: “’I really loved you in Everwood,’ said no one ever.” Later, seemingly referencing the latest X-Men installment, Pratt asks, “How does it feel being in the stupidest Marvel movie?” But Lawrence isn’t fazed: “Where do you keep your Oscar?” Pratt feels that one. He counters with the weakest comeback imaginable: “You were given an Oscar for Best Actress. You would also get one for being the worst.”

Incidentally, Mills’ cohost here is one Chris Stark, whom viral video aficionados will remember from his epic Mila Kunis interview back in 2013.
