What Cohen brings to The Good Thief is the same air of beautiful fatalism he brought to Robert Altman's McCabe & Mrs. Miller (1971) and Atom Egoyan's Exotica (1994).
Tchéky Karyo, my new favorite unshaven French actor (you can see him next week in The Good Thief, Neil Jordan's fun remake of Bob le Flambeur [1955]), plays an endearing French researcher called Sergei, and Stanley Tucci is a hoot as a plummy-voiced prima donna celebrity-scientist who might have inadvertently caused the whole core mess in the first place.
