On Sunday night, Moonlight won the Oscar for Best Picture in whats easily the most memorable moment in the award shows history.

First, the presumed winner for that category, La La Land, erroneously won. Then the Academy slowly informed the room that there had been a mistake and Moonlight had actually earned the award. In what remains an internal mystery , presenters for this final and most prestigious award, Warren Beatty and Faye Dunaway, walked onstage with the wrong card to reveal the winner.

Despite this turmoil, Moonlight deservedly came out on top. In an aggregate for the movies critics thought were the best in 2016, Moonlight was solidly in first place. The movie also got at 98 percent on Rotten Tomatoes .

So how did the people behind Moonlight make such a widely-beloved movie?

In large part, the key was authenticity, which is often the case with great art.

As various creators of Moonlight describe in the above exclusive video provided to The Huffington Post, much care was devoted to basing this movie on reality from start to finish.

Co-screenwriter Tarell Alvin McCraney based the story largely on his early life in Miami, while director and co-screenwriter Barry Jenkins came from a similar situation in Miami. Then, the creators chose to integrate the city deeply into the movie.

Tarells writing just described Miami in a way that I hadnt seen described before, Jenkins said at the beginning of the clip. It was personal.
