An upcoming movie where Jennifer Lawrence plays a woman who has to try and seduce an 'unf**kable' teenager is based on a true story.

No Hard Feelings is perhaps unsurprisingly not really the sort of film you'd take your kids to go and see, but according to the movie's main star it was the 'funniest script I've ever read in my life'.

The basic premise of the movie is that Lawrence's character Maddie is an Uber driver who loses her car to an ex, and needing to get herself a new set of wheels, she answers an advert posted by a couple (Matthew Broderick and Laura Benanti) who want someone to 'date' their socially awkward 19-year-old son (Andrew Barth Feldman).

If Maddie does this she'll get a car so she ends up having to try and seduce a very 'unf**kable' teenager as his parents want to bring him out of his shell. Hijinks quickly ensues.

It's a hell of an idea to pitch to movie studio bosses wondering what Hollywood megastar Jennifer Lawrence's next project is going to be.

Incredibly, the film is actually sort of based on a true story, as No Hard Feelings director and co-writer Gene Stupnitsky told Entertainment Weekly the idea for it all was based off a real Craigslist ad offering very much the same deal.

The director said producers Marc Provissiero and Naomi Odenkirk sent him the advert and it just sparked off the idea for the movie, so someone out there has been trying to pull off the premise of this movie for real.

He said: "You read it, and I thought, 'This is wild. Who is the woman that answers this ad?' And I thought, 'Oh, that'll be a great role for my friend Jennifer Lawrence'."

"Comedies in general haven't really been made that much, especially in the theatrical space. At the time it didn't necessarily feel like we were making a throwback, but I think once people saw the trailer, that was the reaction. I was like, 'Oh, that makes sense.'"

"Gene read the Craigslist ad to me, and I died laughing." Lawrence remembered in her first steps to getting the part.

"I thought it was hilarious, but there wasn't a script or anything. I just thought he had a funny idea. And then a couple years later, he handed me the funniest script I've ever read in my life."

"I guess I like cringe humour. I do like the idea of comedy that makes people uncomfortable. I love when people are watching through their hands, through their fingers. Nothing makes me happier. And I love a lot of the stuff that Harold Ramis did, his movies."

The age gap is already weirding some people out but presumably that's rather supposed to be the point, that pretty much everything going on in this film is weird and even crazier is that some actual human beings thought it was an idea good enough to try.

No Hard Feelings releases in cinemas on 23 June.
