The "notoriously unfinished" final film of Orson Welles, The Other Side of the Wind, is being screened for the first time at the Venice Film Festival this weekend—and will get its North American premiere at the New York Film Festival this fall—before being available on, yes, Netflix. Now the streaming giant has a trailer for the film, which stars director John Huston, director Peter Bogdanovich, Susan Strarsberg, Oja Kodar, Mercedes McCambridge, Paul Mazursky, Henry Jaglom, Claude Chabrol, and many more.

A press release describes the film, and its history, thus:

In 1970, legendary director Orson Welles (CITIZEN KANE) began filming what would ultimately be his final cinematic opus with a cast of Hollywood luminaries including John Huston, Peter Bogdanovich, Susan Strasberg and Welles's partner during his later years, Oja Kodar. Beset by financial issues, the production ultimately stretched years and gained notoriety, never to be completed or released. More than a thousand reels of film negatives languished in a Paris vault until March of 2017, when producers Frank Marshall (who served as Welles's production manager during his initial shooting) and Filip Jan Rymsza spearheaded efforts to have the film completed after over 40 years.

Featuring a new score by Oscar-winning composer Michel Legrand and reassembled by a technical team including Oscar-winning editor Bob Murawski, THE OTHER SIDE OF THE WIND is Orson Welles's vision fulfilled. It tells the story of grizzled director J.J. "Jake" Hannaford (Huston), who returns to Los Angeles after years in self-exile in Europe with plans to complete work on his own innovative comeback movie. Both a satire of the classic studio system and the New Hollywood that was shaking things up, Welles's last artistic testament is a fascinating time capsule of a now-distant era in moviemaking as well as the long-awaited "new" work from an indisputable master.

Besides the amount of film to go through, many parties needed to give their approval. Marshall, who has produced blockbuster franchises (Jurassic, Indiana Jones, and Bourne), told IndieWire, "[Netflix] offered to pay for the post-production and the acquiring of the rights from everybody, which no one had done before,” Marshall told IndieWire.

He added, "This has been a long, agonizing journey, obviously. Finally, when we were able to get into the lab in Paris with the agreement with Netflix, did we really know what we’re up against. They were very flexible with adjusting things to give us what we needed to really finish the movie and that was really great."

According to Deadline's Peter Bart, "Wind is not so much a movie as a gripping collision of two movies: one is an edgy, sexy drama about loyalty and betrayal, the other a satiric faux documentary about the egotism of European filmmakers. In true Welles fashion, they were shot in fragments between 1970 and 1977. Welles didn’t even cast his lead, John Huston, playing a legendary filmmaker, until three years into production. He shot one seven-minute sex scene over the course of two years in three different locations."

Welles, of course, was known for his groundbreaking works, from his radio production of The War of the Worlds to his masterful debut as a filmmaker, Citizen Kane, but, as Bart points out, he was "an inept fundraiser," and his films kept running out of money to complete. Bogdanovish told Bart, "With all its confusions and problems, the shooting of Wind turned out to be the ultimate fun set. Welles saw it all as a take-off on [Michelangelo] Antonioni and his imitators. It was a perfect representation of Orson’s vision of film and filmmakers, reflecting his humor and his sensibility.”

Speaking of Welles's sensibility:

The Other Side of the Wind will been shown at select theaters and be available on Netflix on November 2.
