When two A-list actors who also happen to be total goofballs spend a lot of time together shooting a movie, sometimes their on-set antics get a little carried away – and earn them shushes from their director.
“Yeah, that happened a lot,” Jennifer Lawrence told PEOPLE Wednesday at the Los Angeles premiere of Passengers — the sci-fi/romance in which she stars alongside Chris Pratt. The duo’s playful repartee, regular pranks and chatty chemistry sometimes proved too much of a distraction for filmmaker Morten Tyldum (The Imitation Game) and his crew.
“There were times where we really should have given Morten a break,” she chuckled. “We were all in this together trying to finish this movie, and then we turn Morten into the principal [on the schoolyard]. But yeah. We probably got in the way a couple times.”
“Every once in a while we had to be shushed,” agreed Pratt, 37. “We had a lot of fun. We were laughing a lot. She’s better at switching immediately from goofball mode into serious acting mode, so sometimes I had to kind of shut it down and kind of go inward to get there. She just kind of turns it on and off real quick. So yeah, we got in a little trouble – but not too much.”
Lawrence, 26, said the pair never quite got scolded for their behavior. “No — that’s what happens when you’re famous,” she laughed, adding “[That’s] my advice to you schoolchildren.”
“They were constantly being funny,” explained Tyldum. “I was the serious one, and they were the funny ones. And I’m with the camera, I’m setting up a shot, and I’d constantly hear laughter and things going on, in the chairs where they are sitting.”

But the filmmaker said all the stars’ goofing around helped create a rapport that grounded their characters in reality against the epic, futuristic backdrop and offset the more darkly emotional scenes:
“There’s a lot of big emotional scenes there, and I think to have that levity, to have that playfulness … You can’t be a whole day and go into a day like ‘Today I’m going to hate you,’ and ‘Today I’m going to have a breakdown.’ You can’t go around in that dark cloud all day, so they need this lightness, to have this fun.”
Lawrence says she particularly savored one choice prank on Pratt. “I convinced the whole crew that he screamed like a woman once, because I screamed,” she revealed. “I told everybody it was him.”

Pratt’s been squeezing in his share of burns on Lawrence during the press tour for the film – he regularly posts photographs of himself on social media with the actress half cut out of the shots, and in a video interview together he asked her “How does it feel being in the stupidest Marvel movie?>a?” – but he promises that the worst is yet to come.
“You haven’t even seen it yet,” he insisted. “There’s a good one coming!”
