From wikipedia — The Other Side of the Wind is an unfinished film directed by Orson Welles, shot between 1970 and 1976, and starring John Huston, Bob Random, Peter Bogdanovich, Susan Strasberg and Oja Kodar, and is a satire of both the passing of Classic Hollywood, and the avant-garde film-makers of the New Hollywood of the 1970s.
The film covers the 70th birthday party of movie director Jake Hannaford, who is struggling to make a commercial comeback. It opens with Hannaford’s death just after the party, and mostly focuses on the night before his death. We also see extracts of Hannaford’s daring new film-within-a-film, The Other Side of the Wind. As we learn more about Hannaford at his party, the audience realises that he is a far more complex character than he seems, and harbours several big secrets.
The film presents a cynical portrait of Hollywood in the 1970s, parodying the passing of the studio system, and the experimental new film-makers of the new Hollywood, as well as mocking successful European directors such as Antonioni.
