RONIN opens. Directed by John Frankenheimer. Written by J.D. Zeik and David Mamet (as Richard Weisz). Breakneck, non CGI chase scenes through the streets of Paris and Nice buttress smart, steely action thriller with a grim Robert De Niro heading up a group of ex-CIA mercenaries hired to retrieve a mysterious (McGuffin) suitcase. With Jean Reno, Natascha McElhone, Stellan Skarsgard, Sean Bean and Jonathan Price.
