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

Jennifer Lawrence is not shy about sharing her awkward behind-the-scenes experiences on set.

The Hunger Games actress has enjoyed a stellar career since winning an Oscar for Silver Linings Playbook, however, that doesn't mean the job is always comes easily to her.

Lawrence previously admitted 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.

However, they shouldn’t take Lawrence's actions personally, as she has also admitted to finding it 'really really hard' to film with Jonah Hill in Don’t Look Up - although this encounter thankfully didn't involve kissing.

The Netflix original stars Jennifer Lawrence and Leonardo DiCaprio as two astronomers who must warn the world of an approaching comet that could destroy Earth.

The film was lauded by fans who loved both it's star-studded cast — Jonah Hill, Meryl Streep, Chris Evans and Timothée Chalamet also star — and poignant message about climate change.

In an interview with Vanity Fair, the actress opened up about the process of filming the dark comedy and explained why she found it hard not to burst out laughing while filming with Hill.

Lawrence, who plays astronomer Kate Dibiasky in the flick, explained Hill’s character, Jason Orlean, is ‘the worst’ and it was really hard to not ‘ruin’ every take when filming together.

She said: "It was really, really hard filming with Jonah, and just not ruining take after take, laughing. We one time dedicated an entire day to him just improv-ing insults at me.

"It was amazing."

Commenting on Hill's ability to improv, the Hunger Games star revealed 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 added.

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."
