The Other Side of the Wind

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 a flashy film, laden with gratuitous sex scenes and violence, with mixed results. At the time of Hannaford's 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.
