While Universal Pictures and the filmmakers still haven't decided on an official title for the Untitled Matt Damon Bourne Sequel, the cast continues to grow. Variety reports that Tommy Lee Jones has signed on for Bourne 5, portraying a "superior officer at the CIA." The role is being compared to the characters played by Chris Cooper, David Strathairn, Brian Cox and Edward Norton in the first four Bourne movies.

Tommy Lee Jones will be joined by Matt Damon as Jason Bourne, Julia Stiles as Nicky Parsons and Alicia Vikander, whose role has not yet been revealed. We reported last month that Viggo Mortensen was being sought to portray the main villain, but his involvement has never been confirmed yet. Universal is also moving forward with a separate sequel for 2012's The Bourne Legacy, starring Jeremy Renner, but producer Frank Marshall has confirmed that there are no current plans for Jason Bourne and Jeremy Renner's Aaron Cross to meet in the same movie.

Fans have been clamoring for Bourne 5 ever since the 2007 release of The Bourne Ultimatum. Matt Damon had stated for years that he would not come back to the franchise, unless The Bourne Supremacy and The Bourne Ultimatum director Paul Greengrass returns to the helm. After several years of waiting, the long-awaited action sequel finally came together last September.

Paul Greengrass is directing from a screenplay by Christopher Rouse, with Frank Marshall producing alongside Jeffrey M. Weiner, Gregory Goodman and Ben Smith. Paul Greengrass and Matt Damon are also producing, with Christopher Rouse and Henry Morrison serving as executive producers. Production is expected to begin sometime this summer, with Universal Pictures already setting a July 29, 2016 release date.

Tommy Lee Jones last starred in The Homesman, alongside Hilary Swank. The actor also directed and co-wrote the Western drama which hit theaters back in November. He will next be seen in Criminal, alongside Gal Gadot, Ryan Reynolds, Gary Oldman and Tommy Lee Jones, arriving in theaters next January.
