Why was The Other Side of the Wind not completed during Orson Welles’s lifetime?

Orson Welles was unable to complete The Other Side of the Wind during his lifetime primarily due to financial and legal complications. Although Welles shot and partially edited the film between 1970 and 1976, production stalled when the project ran out of money before postproduction could be finished. Following this, the film became entangled in a protracted legal battle that persisted long after his death. It was not until 2018 that a version of the movie was finally released, utilizing the footage and notes Welles had left behind.1
