Although Matt Damon will not return as Jason Bourne, The Bourne Legacy is bringing back two familiar faces for the new action movie with Joan Allen and Albert Finney returning to the franchise.

Joan Allen will portray Pam Landy and Albert Finney is set to play Dr. Albert Hirsch, both of whom are key members in the Treadstone program. It isn't clear as of yet how these characters will come into play in The Bourne Legacy. Jeremy Renner has already signed on to star as another pupil of the Treadstone program, not Jason Bourne.

Tony Gilroy, who wrote all three movies in the Jason Bourne trilogy, The Bourne Identity, The Bourne Supremacy, and The Bourne Ultimatum, will write and direct The Bourne Legacy. Rachel Weisz and Oscar Isaac also star, with Edward Norton in talks to portray the villain.
