Beatrice Prior must confront her inner demons and continue her fight against a powerful alliance which threatens to tear her society apart.

It's not like "Divergent" fans had any real reason to worry about their franchise getting a sequel, seeing as Veronica Roth's books are a trilogy and Lionsgate had a follow-up planned all along. But just in case anyone was uncertain, Lionsgate subsidiary Summit Entertainment has officially given "Insurgent" the green light.

Really, though, we had nothing to fret over. The Shailene Woodley-fronted dystopian flick opened to an impressive $4.9 million following Thursday night's screenings. While the movie is no longer poised to be more lucrative than the first "Twilight" installment, it's still generated an endless cycle of buzz in recent months and could accrue between $50 and $60 million this weekend.

“We're off to a great start with strong numbers from all regions of the country, urban, suburban and rural alike,” Lionsgate CEO Jon Feltheimer said in a statement. ”We're confident that ‘Divergent' is on its way to becoming another important franchise for us, and we have just greenlit the second film, ‘Insurgent.'”

As previously announced, "Divergent" director Neil Burger won't return for the sequel, having turned down the offer for "practical reasons" concerning his shooting schedule. Instead, Robert Schwentke ("The Time Traveler's Wife," "R.I.P.D.") will take over. "Insurgent" is eyeing a March 2015 release, and Woodley and co-star Theo James are already on board to return.

If the movies stick to that schedule, the third installment, “Allegiant,” will arrive in March 2016.

Naomi Watts has signed on to join the next three films in Lionsgate's Divergent franchise.

The actress, who recently committed to star in Gus Van Sant's Sea of Trees opposite Matthew McConaughey, is joining the cast of Divergent sequel Insurgent as Evelyn, leader of the Factionless. Watts' deal calls for to co-star in the futuristic franchise's two final movies, which are based on Veronica Roth's YA novel Allegiant, the final book in the Divergent trilogy.

Watts will jump right to Insurgent, which began shooting last week in Atlanta. Shailene Woodley, Theo James, Ansel Elgort, Kate Winslet and Miles Teller -- who all appeared in Divergent -- return for the sequel. Watts joins Octavia Spencer as new additions to the cast. After Insurgent wraps in September, Watts will move on to Sea of Trees, which will take her through November. The in-demand actress is mulling a number of films after that.

Robert Schwentke, who replaced Divergent helmer Neil Burger, is directing Insurgent from a screenplay written by Brian Duffield and Akiva Goldsman.
Red Wagon's Doug Wick and Lucy Fisher are producing alongside Pouya Shahbazian.

Insurgent puts Watts, who typically gravitates toward indie projects with auteurs, in the YA tentpole game. Divergent, which opened March 21, has earned $267 million worldwide. Still, she is no stranger to commercial films, having starred in Peter Jackson's King Kong and The Ring films. Watts has three films awaiting release: Alejandro Gonzalez Inarritu's Birdman, The Weinstein Co.'s St. Vincent -- opposite Melissa McCarthy -- and Noah Baumbach's While We're Young.
