Knowledge 1: The Bourne Betrayal
The Bourne Betrayal is the title for the novel by Eric Van Lustbader and the fifth novel in the Jason Bourne series created by Robert Ludlum. It was published in June 2007. It is Lustbader's second Bourne novel, following "The Bourne Legacy" that was published in 2004. Lustbader has written a sequel to "The Bourne Betrayal" titled "The Bourne Sanction". [SEP] Knowledge 2: The Bourne Legacy (film)
The Bourne Legacy is a 2012 American action thriller film directed by Tony Gilroy, and is the fourth installment in the series of films adapted from the "Jason Bourne" novels originated by Robert Ludlum and continued by Eric Van Lustbader, being preceded by "The Bourne Identity" (2002), "The Bourne Supremacy" (2004), and "The Bourne Ultimatum" (2007). Although this film has the same title as Van Lustbader's first "Bourne" novel, "The Bourne Legacy", the actual screenplay bears little resemblance to the novel. Unlike the novel, which features Jason Bourne as the principal character, the film centers on black ops agent Aaron Cross (played by Jeremy Renner), an original character. In addition to Renner, the film stars Rachel Weisz and Edward Norton.
