IMDB may have the director of 2017’s Justice League as Zach Snyder, but that was far from his original film.
The origins of the “Snyder Cut” are now well known: When the film was being finished in early 2017, Snyder had to back out after the tragic suicide of his daughter, Autumn. Joss Whedon (who helmed the first two Avengers films for the MCU) stepped in, and the film was changed drastically. The film’s 4 hour run time was basically cut in half to two, the tone of the film was much lighter, and composer Thomas Holkenborg (better known as Junkie XL) was replaced by Danny Elfman.
