Today I went into a rabbit hole searching for an open source free Movies Database. I found a couple that would satisfied.

  1. mbdip.com- They have a developers sections, but it not well documented.
  2. rapidapi.com/rapidapi/api/movie-database-imdb-alternative/pricing- This would be ok, but I would not set it as reliable.
  3. stackoverflow.com/questions/1966503/does-imdb-provide-an-api- has some really good insight
  4. datasets.imdbws.com- LARGE datasets of movie collection for FREE!
  5. omdbapi.com- The best solution if you  are playing with data. It has a handy JSON API which you can sign up for free or give money as a Patron. If you can afford it, you should give money to them. Having online services is expensive. (even this blog costs money)

Beware that 2-5 are unstable version and could change at any time, if you are building a foundation for an entertainment application, it is best to sign up with a robust and reliable source. Unfortunately, that sources is AMAZON AWS ATHENA. (aws.amazon.com/athena)
