Naomi Watts is set to star in the next three Divergent films.
The Diana star has joined the cast of the sequel Insurgent as Evelyn, leader of the Factionless, a role she will reprise in the other two films in Veronica Roth's futuristic franchise, said The Hollywood Reporter.
She is expected to start shooting her scenes shortly for the second instalment, which began filming in Atlanta last week.
Shailene Woodley, Theo James, Kate Winslet and Ansel Elgort have reprised their roles from the first film, with Octavia Spencer a new addition to the cast.
Robert Schwentke is directing Insurgent from a screenplay written by Brian Duffield and Akiva Goldsman.
Naomi, last seen as Diana, the Princess Of Wales in Oliver Hirschbiegel's drama, will next star in Alejandro Gonzalez Inarritu's comedy Birdman, comedy St Vincent opposite Chris O'Dowd and Melissa McCarthy, and Noah Baumbach's drama While We're Young.
The 45-year-old actress is also attached to star in Gus Van Sant's Sea Of Trees opposite Matthew McConaughey.
