Kate Winslet isn't someone we usually identify with big franchise movies, mainly because she doesn't do them very often. She's had more than a handful of blockbusters, but for the most part she's remained tentpole free for the bulk of her career. So one would expect it takes something really special to lure her into that territory, and apparently she sees those qualities in Neil Burger's adaptation of Divergent.

Last we heard, Alex Pettyfer, Jeremy Irvine, and Lucas Till were vying for the male lead, presumably as Beatrice's instructor and lover Tobias Eaton, but the studio has decided to go older for the role so those names may be off the table. They might make for a better fit as her older brother, Caleb.
Divergent is expected to hit theaters on March 21st 2014.
