Based freely on the writings of Hoseyn Qoli Khān Nuri, Persia's first ambassador to the United States (1888–1889), Haji Washington (1982) was Ali Hatami's first feature film following the Islamic Revolution. This article explores Hatami's departure from historical record in light of his aesthetic and political appropriation of Nuri's image as a failure. Viewing the film through a methodology that recasts failure as decolonial praxis beyond post/colonial mastery, I argue that Haji's embrace of failure, and his ultimate adoption of relationality as a mode of worldliness, constitute a “decolonial aesthetics of failure” with broad implications for both the world of the narrative and the moment of the film's production in postrevolutionary Iran.
