Thanks to the phenomenal success of the Jason Bourne film juggernaut in recent years, Hollywood has kept calling on the late Robert Ludlum's novels for more "projects to head to the multiplex and reinvigorated the author's status with a new generation of readers, not to mention inspiring new video games," according to USA Today.
In addition to "Untitled Jason Bourne 4," other Ludlum books currently being developed as film projects include The Matarese Circle, in which "Denzel Washington plays a CIA agent, and Tom Cruise is negotiating to play his Russian rival," The Chancellor Manuscript, for which "Leonardo DiCaprio's representatives say he is looking to produce and star," The Parsifal Mosaic, The Sigma Protocol and a remake of The Osterman Weekend.
