Josh Zetumer is set to write Universal's fourth installment in the Jason Bourne series, writing what is being described as a parallel script, says The Hollywood Reporter.

George Nolfi, who worked on The Bourne Ultimatum, initially came back for the fourth entry. But as that movie nears its September start date, Nolfi had to step away and Universal hired Zetumer to write a new script. It is unclear what will occur after Zetumer submits his draft or whether his script will be integrated with Nolfi's.
