Yes, it can be done
I have a friend (that made the bad mistake of asking a sex related question here on this forum, the moral police came down and hard on him) that got himself a lawyer here in the DR and asked all the questions, about films, brothels, sex workers, ect..
The lawyer he got was not a nickel and dime "Pica Pleitos" man but a lawyer with years of profession and respected background.
The lawyer informed him as to the adult movies.
1) Get the cedulas and Birth Certificates of the models you will use, male and female, get 2 copies, verify the cedula at the JCE before you start.
2) Do not under any reason film in public locations, don't even try to pay location tax because you have to inform what movie you are making and it's more of a hassle then it's worth it.
3) Make sure your film company is a foreign entity not a local company.
4) You as a person cannot live in the DR. This is just to protect your assets from mafia type law (people that want a bribe all the time for no reason).
5) Make sure you get a Model release form and video tape the model reading, understanding and signing the form. That way they cannot claim they did not know what they are getting into.
6) For Internet content the DR is not recommended. Just Videos and DVD sales.
7) Do not film Child, Animal and Extreme Sex movies. There are several codes against that.
8) Gay films are ok just make sure the same as above. (Why he asked I don?t know I think it was for FF action films.)
9) Do not advertise for models on the newspaper since this may attract unwanted people (Minors the most).
Go out, hang at bars and carwashes and play the field to fine the girls. Bit-by-Bit they will come and grow.
I hope this helps, just go and ask a Good Lawyer and ask the right question and get ready to pay lots of money to the lawyer.
I hope this helps.
