Norton: 'Bourne' director has taken franchise 'to another level'

Edward Norton says the 'Bourne' films are more "authentic" than other blockbusters.

The 42-year-old actor - who stars as antagonist Eric Byer in the 'The Bourne Legacy' - believes the Tony Gilroy-written film franchise is much more realistic than rival motion pictures such as 'Mission: Impossible' and the James Bond series.
