I'm not seeing any adult movies returned here:

https://api.themoviedb.org/3/movie/popular?api_key=###

What query are you making, and what is the movie in question?

hmm sorry i said popular , i should say top rated movies. My query is

https://api.themoviedb.org/3/movie/top_rated?include_adult=false&api_key=###

We have a porn movie and after "serious" movies like "The Godfather", "The Shawshank Redemption", "The Schindler List" ... You can see the list on my website if you want (on the left frame) : https://www.cine-phil.fr/en/

just a precision, i put the include_adult as FALSE it doesn't change anything

I'm not seeing it here either:

Actually i put the include_adult on "false" but I had to delete it completely of my query. To put it on false is not working Thanks and sorry ... my fault

Got it.

Doesn't look like that is a supported param on the popular/top rated/now playing/upcoming methods. It's not documented. Something weird is happening if you specify it, but it shouldn't be used at all.

Leave it off and you'll get the data you expect.
