CHRIS Pratt and Jennifer Lawrence were "shushed" like children on the set of 'Passengers'.
The 37-year-old actor and his 26-year-old co-star have admitted they took turns pranking each other whilst filming and promoting their new movie, but the fair-haired hunk has hinted he found it harder to stay serious in comparison to Jennifer, whilst shooting scenes for the science fiction film, and was often told to stop the gags.
He told PEOPLE: "Every once in a while we had to be shushed. We had a lot of fun. We were laughing a lot. She's [Jennifer] 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."
The blonde beauty - who plays the role of Aurora Dunn in the romantic thriller - has admitted director Morten Tyldum wasn't amused by the duos antics and thinks her and Chris "got in the way".
The 'The Hunger Games' star explained: "Yeah, that happened a lot, 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."
However, the 49-year-old creative mastermind has admitted he wasn't annoyed by his cast because he claims their humour brought balance and "lightness" to the production.
He explained: "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.
"I was the serious one, and they were the funny ones."
