Actor here. Doing intimacy scenes is surprisingly difficult, arguably more so than combat, because usually people train and get certified in sword and dagger, rapier, firearms etc to get cast

When working a job, putting your mouth on another person’s mouth is a very unusual act, and you want your actors - regardless of gender - to feel safe, comfortable, professional and not exploited - not to mention you might spend 2x 14 hours days on this sequence from multiple angles getting it the same every time

That’s someone whose job is to liaise and advocate for actors to the production crew for intimate scenes, especially nude and sex scenes.

People who help other people who work on scenes that involve intimacy to make the whole process as pleasant as possible for everyone involved.

It’s a somewhat new job title, but it’s now becoming standard across the movie industry.
