The Other Side of the Wind is a 2018 satirical drama film co-written, co-edited, and directed by Orson Welles, and posthumously released after 48 years in development. The film stars John Huston, Bob Random, Peter Bogdanovich, Susan Strasberg, and Oja Kodar.

Intended by Welles to be his American directorial comeback after years spent abroad, the film began shooting in 1970 and resumed on and off until 1976. Welles continued to work intermittently on editing the project into the 1980s, but it became embroiled in financial, legal, and political complications which prevented it from being completed. Despite Welles' death in 1985, several attempts were made at reconstructing the unfinished film. The unreleased results would be called "the Holy Grail of cinema". In 2014, the rights were acquired by Royal Road and the completed project was overseen by Bogdanovich and producer Frank Marshall.

The story uses a film-within-a-film narrative which follows the last day in the life of an aging Hollywood film director (Huston) as he hosts a screening party for his unfinished latest project. Using color and black-and-white footage, the film was shot on 8 mm and 16 mm in an unconventional documentary style, featuring a rapid-cutting approach between the many cameras of the story's numerous journalists and news-people. It was intended among other things as a satire of both the passing of Classic Hollywood and of the avant-garde film-makers of Europe and New Hollywood in the 1970s.

The Other Side of the Wind had its world premiere at the 75th Venice International Film Festival on August 31, 2018, and was released on November 2, 2018, by Netflix to critical praise, accompanied by a documentary, They'll Love Me When I'm Dead.

Set some time in the early 1970s, the film opens by describing the final day of Jake Hannaford, an aging Hollywood director who was killed in a car crash on his 70th birthday, with narration from an elderly Brooks Otterlake, who had been a protégé of Hannaford's. Just before his death, Hannaford was trying to revive his waning career by making an experimental film, laden with gratuitous sex scenes and violence, with mixed results. At the time of Hannaford's birthday party, this film (titled The Other Side of the Wind) has been left unfinished after its star stormed off the set, for reasons not immediately apparent to the audience.

A screening of some incomprehensible parts of Hannaford's unfinished film takes place, in order to attract "end money" from studio boss Max David. Hannaford himself is absent, and a loyal member of his entourage, the former child star Billy Boyle, makes an inept attempt to describe what the film is about. Intercut during this, we see various groups setting out for Hannaford's party at an Arizona ranch. Hannaford arrives with a young Otterlake, a commercially successful director with a talent for mimicking celebrities, who credits much of his success to his close study of Hannaford.

Many journalists attending the party brandish cameras and ask invasive questions, eventually querying Hannaford's sexuality and whether he has long been a closeted homosexual, in spite of his macho public persona. Hannaford has a history of seducing the wife or girlfriend of each of his leading men but maintains a strong attraction to the leading men themselves.

Several party guests comment on the conspicuous absence of John Dale, the star of Hannaford's latest film, whom Hannaford first discovered when Dale was attempting suicide by jumping into the Pacific Ocean off the Mexican coast. As the party proceeds, Hannaford finds out that Dale's suicide attempt had been faked and that he had actually set off to Mexico to find Hannaford. Guests are shown more scenes from the film at the ranch's private screening room. One scene makes it clear why Dale left the film—he stormed off the set in the middle of a sex scene in which he was being goaded by Hannaford off-screen.
