The East (2013)

A successful operative for an elite private intelligence firm is tasked with infiltrating an anarchist group known for executing covert attacks upon major corporations. However, she finds her priorities changing as she befriends the members and begins to develop romantic feelings for its charismatic leader.

Hey, wake up IMDb reviewers. Hiller Brood, the security firm that is half the focus of The East, is based on Booz Allen, the Chicago firm that is the largest private spy company in the world and that supplied Edward Snowden with his felicitous job at the NSA. Business Week's site has a good summary article on their business model.

Also: every review I've read seems to think the female lead's terrorist love interest, played by Alexander Skarsgård, is the group's leader, despite the only slightly subtle dig at that expectation the movie provides, when the infiltrator calls him the leader and gets surprised looks, after which the Ellen Page character is shown to exercise the most influence. (Hey, they're anarchists, no leaders, duh!)

Don't know why some reviewers think the movie doesn't take a stand on the issue at its core: the morality of retaliation against corporate wrongdoing. The terrorists (and infiltrator) are young, good-looking and thoroughly moral, while their corporate enemies are ugly, brutish and thoroughly unpleasant, tho they have, of course, the law, and all its apparatus, firmly on their side.
