Ronin (movie)

Ronin is a 1998 film which tells the story of a group of former intelligence agents who team up to steal a mysterious metal case... but can they keep from trying to keep it for themselves? It stars Robert De Niro, Jean Reno, Natascha McElhone[?], Stellan Skarsgård[?], Sean Bean[?] and Katarina Witt.

The movie was written by J.D. Zeik[?] and David Mamet, and directed by John Frankenheimer.

David Mamet served as a script doctor on the screenplay, being billed as "Richard Wiesz". The Writers' Guild refused to allow him to get top billing for the writing credit, so he refused to allow his real name to be used.

As analogy, the title Ronin is the name under which samurai who's master was killed were known.
