THR is reporting:
With the movie now being rewritten by Abrams and Lawrence Kasdan, sources say producers also are looking to fill a new role: a 40-something military man a la Matt Damon in Elysium.
I have to say, this isn’t really news as he was listed in the first casting call back in June:
Forty something male, fit, military type.
It might appear they are actually actively seeking to fill the role now, however.
