Отказывается находить любой фильм.
Делаю запрос на search/multi даже через ваш developer docs, и он возвращает 0 результатов. В независимости от фильма и того как я его ввожу.

Google Translate

Refuses to find any movie.
I make a request to search/multi even through your developer docs, and it returns 0 results.
Regardless of the movie and how I enter it.

Problems with API Request

In order for someone to help you with API Request questions,
it is critical that you post here the API Request you are sending to the TMDb server.
Remember to replace your Key with MY_KEY , YOUR_KEY , THE_KEY , or something like that.

Not the programming code/script you used to build the API Request.
But the API Request that is sent to the TMDb server.
Or the API Request you would like to send.

Example
