The film deals fleetingly but tellingly with the almost unconscious corporate resistance to his suggestion and among the things the reporters dig up is evidence of their own past failures. This willingness to detail the paper's shortcomings, as well as its triumphs, lend the story credibility that money can't buy.
Crucially, too, it avoids obvious flashbacks to scenes of creepy priests, although the brief sequences of witnesses have a visceral jolt ("How do you say no to God?" one man asks, trying to explain his compliance).
Indeed, the confronted guilty parties are almost nonchalant ("Sure, I fooled around," one says. "But I never gratified myself.") and their superiors, who want to starve the story of oxygen, are chillingly reasonable about it all.
In the end, it's an ensemble piece and the ensemble work is first-rate. Mike Rezendes (the always likeable Ruffalo), his head perpetually thrust forward like a dog straining at the leash; and Sacha Pfeiffer (resolutely unglamorous McAdams) are the stars but Matty Carroll (James) and boss Walter Robinson (Keaton), constantly fighting their corner in the corridors of management, are essential parts of the whole.
Tucci, perhaps the most consistently enjoyable of American actors, is wonderful as a lawyer whose attention to the case moved beyond obsession into imprisonment, and Crudup as another lawyer is eerily plausible.
This is an important film driven by a powerful, almost palpable, sense of moral urgency. It's also, not incidentally, an elegy for what newspapers used to be.
