Now of course, when you boil down to it, there are all sorts of dangers in a theatre or on a film set, and not just linked to people, but in this one, we will be looking simply, at the sexual safety of actors.
Now, as an actor myself, I have encountered problems. In my early twenties, I went for an audition that I found online, it all seemed OK and legitimate, the guy clearly knew all the "right" answers, at a "studio" - turned out to be someones house - and after being locked in a room, I ended up departing through the window. Luckily, that was my scariest experience, though I often get social media messages from guys thinking that messaging an actress, means they are on to some promiscuous woman who is going to do "anything". Nothing could be further from the truth (as they are emphatically informed, a few seconds before being blocked!).
When casting projects, on the other hand, I have, over the years, had applications from ladies, who, (presumably not realizing that I am female) have sent explicit photos of their nether-regions, and comments like "I love to cook for men" and "I will do anything for this role, please see my attached photos". I have also had guys send nude pictures for the same reason (not the laughable dickpics, but posed nudes).
Sorry to say, those applications end up in the proverbial bin, but it has its sad side. People should not feel that they have to prostitute themselves to get a role.
More infuriatingly, again over the years, I have had a small but upsetting number of people join productions who have been seeking various .. shall we say.. romantic hookups, or who have been unable to respect peoples personal boundaries. They have usually been rather surprised and not a little disappointed, when asked to leave! One person actually told me they had hoped we were a front for a swingers club, and were taken aback, not to mention extremely disappointed, when we proved to be exactly what we claim to be, a team of people creating theatre and film projects.
Sometimes acting - and modeling - does ask for nudity or implied nudity for some roles. They are rare but not unknown with our team. As a director, if a role asks for something like that I am extremely careful to state that upfront, check the ages of everyone involved or present in the scene, and make sure that during filming / performance and rehearsals that we have a DBS-checked safe-guarder (I dont care that we are all adults, safeguarding is still a thing that I think is critically important) present, and that all actors are repeatedly asked to not cross any personal comfort zones, and to say immediately if unhappy or uncomfortable with anything. As an actor, leaving aside the fact I am not in any way a supermodel, I have done these kind of roles, and I consider such jobs very carefully - if I am auditioning for a role that involves these, I check out the company carefully. Do they have an established track record? Who is present at the time? Where is it being done? Only if I am completely comfortable, do I even audition.
In our auditions, I never mind if someone brings a friend the first time they come to meet us. If someone is under 16 I insist on attendance with a parent. When I am going for an audition, I always inform people (usually my mother, and my fiance) exactly where I am going and what I am doing. As a rule for auditions, do not go to a private house or hotel room. (I also know of actresses who have been invited to airports and ferry terminals for auditions - which is a big people-trafficking risk). Our auditions (and rehearsals) take place in a known community centre. Sometimes they happen in theatres, studios, anywhere, but wherever it is, make sure it is a public space. I have indeed been to an audition in a hotel, but it was in a lounge with other people, not someones room upstairs.
The most important thing is communication, and never being afraid to discuss with the production team if you have a concern, or something has happened. Sometimes we have a new intake of people and someone comes in that intake who does not act appropriately. The admin team need to know - if we spot something we act but sometimes these things are happen away from our attention, and then we need to know , with any screenshots or anything like that if it has been online. Dependent on the situation and evidence, we may speak with the person and give a warning, or remove them from the production entirely. We would involve the Police if needed.
What is really important is keeping everyone safe and happy, and removing the culture where people feel they have to sacrifice their personal self respect in order to get ahead.
If you are in an production somewhere where the production team themselves are the ones causing the issue, and not simply one person, with a culture of disrespect, then you shouldn't feel that you cannot approach the Police with evidence. If it is something where we have taken on external work through our agency, and it is not an issue the production team are willing to tackle, then we fully support our actors walking away from the project.
Its idealistic. I know it is. Plenty of the darker side of the showbiz world happens still and probably will do so, but the more people, both individual actors, and production teams, who take a stand against it, and realise that it is perfectly okay to tell someone "no" and that the production team will support them on that, and have zero tolerance of such behaviour, the better.
The days of the casting couch, still sadly do happen in the showbiz world, and we all need to work together to make sure it gets stamped out and that nobody makes, or feels obliged to accept, such advances.
And while I have spoken about sexual boundaries being crossed or inappropriate behaviour in that vein, and the ways in which I keep safe in that vein, the same should go for any kind of bullying.
For actors, you may find this article on Mandy.com, helpful
For models, you may find Safemodel helpful, and they are always very responsive with advice if you contact them with a question. (while mainly geared to models, actors are also able to approach Safemodel, I have done myself).
