Someone had to digitally add pubes to Dakota Johnson in the 50 Shades movies
If you’re not familiar with how they film sex scenes, it’s pretty awkward, with the little flesh flaps/covers over the uglies they’re bumping. While there is a lot of nudity in the film, there’s also a lot of trickery involved to make it look safe, hygienic and legit.
Most of the sex scenes that were shot in the first film especially, had the flesh shield on full display. In post production, someone had to add in the foliage to make it all look natural.
