Ruiz returned to Portugal, the locale of many of his films, to adapt Dostoevsky’s The Eternal Husband, and the end product, Fado, Major and Minor, is among the most elliptical and intriguing works in his filmography. Jean-Luc Bideau stars as a tour guide who after blacking out returns to his apartment to find a mysterious intruder (Melvil Poupaud) who holds him accountable for the death of his lover. After premiering at Cannes, the film all but vanished due to rights issues, but it endures for Ruiz’s toggles between tragedy and farce, black and white and color, pop music and the traditional fatalistic sea shanties of its title.
