Alicia Vikander is also in talks to join the cast. Sources have told Variety that Viggo Mortensen was holding the offer to play the assassin tracking Bourne but has not confirmed whether he will be joining the cast.
Frank Marshall will return as producer along with Damon, Greengrass and Jeffrey Weiner.
Plot details are unknown at this time, though it’s likely that Stiles will be reprising her role of a former CIA operative who teams up with Bourne.
The pic will bow July 29, 2016.
Damon’s three Bourne movies, which began in 2002 and ended in 2007, grossed nearly $1 billion worldwide at the box office.
Stiles is repped by ICM Partners and Untitled Entertainment. The news was first reported by Deadline Hollywood.
