A chain of coincidences brings the 13-year-old schoolboy Werner Herzog together with Klaus Kinski to the same apartment in Munich. In an unabated, 48 hour fit of rage, Kinski immediately proceeds to lay waste to all the furniture, only one of such fits to come. Herzog therefore knows what awaits him when, some years later, he engages Kinski to work with him on Aguirre, The Wrath Of God, their first film together. Four more films would follow. My Best Fiend is a film about the love-hate relationship between director Werner Herzog and Klaus Kinski - utterly puzzling to others. It reveals the deep trust between two exceptional artists and their independently and simultaneously hatched plans to murder one another.
