In 2017, director Zack Snyder left the production of 'Justice League' following a family tragedy. The studio hired Joss Whedon to finish the film, resulting in a theatrical version that was panned by fans. This sparked the #ReleaseTheSnyderCut movement—the most significant instance of fan activism in Hollywood history. For three years, fans bought billboards in Times Square, flew planes over Warner Bros. studios, and raised over $500,000 for suicide prevention in Snyder's daughter's honor. In a first for a major studio, Warner Bros. eventually spent an additional $70 million to allow Snyder to finish his four-hour version, which was released on HBO Max in 2021. This proved that in the digital age, fan communities can have a direct, tangible impact on the creative decisions of multi-billion dollar corporations.
