Jennifer Lawrence admitted it was 'really really hard' filming with Jonah Hill

Jennifer Lawrence has revealed why she struggled to film with Jonah Hill on the hit Netflix film Don’t Look Up.

The Hunger Games star, 34, appeared alongside actor and comedian Hill in the hugely popular movie which sees two astronomers attempt to warn humanity about their impending doom at the hands of a rapidly approaching comet.

Don’t Look Up had all the makings of a black comedy classic, from its stacked ensemble cast to appt observations towards our attitudes to climate change. However, it turns out that Lawrence had a difficult time on set in her scenes with Hill.

Sharing the anecdote with Vanity Fair, the actress – who played astronomer Kate Dibiasky – struggled to keep a straight face when filming with the Superbad actor, who played White House Chief of Staff Jason Orlean.

"It was really, really hard filming with Jonah, and just not ruining take after take, laughing,” she said.

“We one-time dedicated an entire day to him just improv-ing insults at me. It was amazing."

Lawrence went on to praise Hill's talent for improv, adding that 'he and 'Meryl were the only ones who should do that kind of improv.'

"I mean, he's just a comedic master. I mean we all did some [improv] just not as well as Jonah," she said.

One scene which didn't feature in the script shows Hill's character telling Lawrence and DiCaprio's to: "Sit tight and assess."

"The sit tight comes first then you've got to digest it, that's the assessment period," Hill says.

Lawrence reflects: "See? That wasn't in the script Jonah."

But, while filming Don't Look Up sounded like a barrel of laughs, J-Law reminded readers that its sentiment is a lot more serious.

When asked what the 'biggest thing' people take away from the movie should be, she replied: "To stop handling information the way that we do now, where there's like the truth and science and then politics, or you know, personal feelings involved.

"You know, we should all just be on the same page of, you know, taking care of our planet, and taking care of mankind.

"World peace would be my hope."

This isn’t the only time Lawrence has opened up about her behind-the-scenes experiences on set, previously admitting that she needed to get ‘tipsy’ in order to kiss Chris Pratt in 2016 sci-fi romance flick Passengers to overcome shyness.

It’s even been reported that the actress makes things equally uncomfortable for her co-stars as well, with The Hunger Games' Liam Hemsworth admitting she would eat foods such as garlic or tuna and then not brush her teeth before the pair locked lips.

Luckily for Hill, his interactions with Lawrence didn’t involve any kissing.
