In an interview Matt Damon said:
“I would be shocked if there was another movie,” he says. “I know the studio wants to do it. The only reason that I can’t promise is if Paul Greengrass came to me in 10 years and said, ‘Listen, I have a way to do a fourth movie that speaks to the world we’re in today’. Then I’d go, ‘OK, this doesn’t corrupt the trilogy’.”
Quite old Bourne it’d be.
Just a lil’ memo from me: The Bourne movies are book adapaions. There is one book left, The Bourne Legacy.
