Premise: Les Enfants jouent à la Russie (English: "The Kids Play Russian") is a 1993 French film directed by Jean-Luc Godard and starring László Szabó and Godard. Szabó plays a Hollywood producer who hires a famous French filmmaker (Godard) to make a documentary about post-Cold War Russia. Instead the filmmaker stays in France and casts himself in the lead role of Fyodor Dostoyevsky's "The Idiot".
Hypothesis: Godard did not write "The Idiot".
