Edward Norton has said that he believes the Bourne film franchise is more "authentic" than other blockbusters.
The 42-year-old actor, who stars as antagonist Eric Byer in latest instalment of the franchise, The Bourne Legacy, said that he believes Bourne is more realistic than rival films such as Mission: Impossible and the James Bond series.
He told Digital Spy: "I think they've always pulled a little more from the authentic reality of what we glimpse in the headlines.
"You've got sort of like the Mission: Impossible or James Bond, which I would call more in the fantasy superhero genre.
"Nobody was ever going to climb a building in gecko gloves, or parachute in a car out of a plane. There were always much more lo-fi."
Norton added that writer-director Tony Gilroy has taken the series to another level with The Bourne Legacy, saying: "Tony's gone even one step further in this one, in the sense that he's opened it up to start to include government-based science.
"He's really starting to kind of exfoliate the way the matrix of government, science, corporations and military comes together.
"Tony kind of peeks behind the curtain and shows us what that's like inside."
