The narrative architect behind the "Bourne" film series, Tony Gilroy, takes the helm in the next chapter of the hugely popular espionage franchise that has earned almost $1 billion at the global box office: "The Bourne Legacy." The writer/director expands the "Bourne" universe created by Robert Ludlum with an original story that introduces us to a new hero (Jeremy Renner) whose life-or-death stakes have been triggered by the events of the first three films.
