The Bourne Legacy was made after Matt Damon dropped out, due to Universal Studios deciding to change directors. Nuff respect to Matt for standing up for his friend, who had done excellent work (IMHO) with the previous three Jason Bourne adventures. Universal then got Jeremy Renner to star as his replacement, and filled out the cast with Rachel Weisz and Edward Norton ! So far it appears the studio was going to win this battle of wills...
