Director: David Zellner. Cast: Rinko Kikuchi, Nobuyuki Katsube, Shirley Venard. 105 min. Drama.
Confession: I've never understood the value of the movie Fargo. I've never been able to relate. So the setting of Kumiko, the story of a lying, stealing, delusional Japanese girl who becomes obsessed with travelling all the way from Tokyo to freezing Minnesota to find the money suitcase buried in the snow at the end of Fargo, was already a loser to me; I empathize with cinema obsession, not with dysfunctional/psychotic obsession. But this movie achieves the strange goal of successfully portraying that delusional obsession (as A Beautiful Mind did). So be warned: the ending might make you angry.
Update (6/29/2015): Here's a documentary about the real Kumiko. Thank you, Toast.
