Tony Gilroy explains the changes made to the Bourne film franchise in new movie

The action-packed Bourne film franchise is back, but this time without the character Jason Bourne or the actor Matt Damon. Instead, "The Bourne Legacy" expands on the original trilogy with a new hero named Aaron Cross, played by actor Jeremy Renner.

An agent of "Operation Outcome," Cross finds himself in a life-or-death situation in which he must save the life of a beautiful doctor, portrayed by actress Rachel Weisz.

Director and co-writer Tony Gilroy, who also wrote and worked on the original Bourne movies, joins Starting Point today to discuss the film and to explain the various changes his team made to the Bourne franchise.

"The Bourne Legacy" opens in theaters next week.
