Coming from someone who has only watched the Bourne series and never read the books, it came as a great surprise to me that Jeremey Renner is playing a different character in The Bourne Legacy.
Is there a specific production reason why they changed to a different character like Matt Damon or even the writers getting bored of Jason Bourne. Or is it as simple as the production wanting to tell this tale from someone else affected by the Treadstone program?
