Hollywood studios usually wait to see at least a full weekend of a given movie's box-office returns before approving sequels. But in the case of Divergent, Summit/Lionsgate is feeling pretty dauntless.

After the movie gained an eye-popping $4.9 million in receipts for Thursday late-night screenings alone, the studio has greenlit Insurgent, the second installment of the dystopian young-adult franchise (is there any other kind?) adapted from Veronica Roth’s best-sellers.

The sequel will begin shooting next month, and is tentatively scheduled for next March.

The early surge for Divergent suggests a $50 million-or-better weekend for the movie, starring Shailene Woodley and Theo James. Some observers are suggesting returns as high as $65 million — making it just the latest YA hit from the studio that brought you the Twilight and Hunger Games sagas.

And you can pretty much take it to the bank that a movie version of Allegiant, the third and final book in Roth’s trilogy and tentatively set for 2016, will be greenlit too.

For now, Summit/Lionsgate has resisted the temptation to split the final book into two films, as it did for “The Hunger Games” and “Twilight.” But if the first two films do gangbusters business at home and overseas, look for that announcement. It’ll likely feature a quote along the lines of “We just couldn’t fit the rest of the story into one film.”
