Dove explained in the article, that; "they must get it 'right'" and "Like getting it right, making everybody happy, and also making sure that it translates. It's so specific."
she also said "To modernise it and to make it fit, like, a bunch of different things that don't normally go together, it's just kind of like a puzzle piece. So we're removing some elements and we're replacing others."
and most importantly "I think the script is going to get another whack, and it's just going to be a slightly different approach but everything else is going to stay the same."
so we should still expect to see all the sex scenes in it just done with a more serious tone to it like the one of her with her ex-fiancé fucking in the nightclub and that other one mentioned of her fucking these two dudes in her bedroom at her house party
