The Cotton Club
Francis Ford Coppola wanted to tell the story between Black and white performers who both performed in a Harlem nightclub. He faced pushback from his investors and was forced to cut out a good chunk of what he felt were important parts of the story. This was all in 1984. In 2017, he ended up rewatching a beta version of the film that he had kept on an old tape and realized that he had royally messed up his own film. He invested $500,000 in reissuing the film into a director's cut, which quickly brought the movie into higher ranks.
