Alex Gibney (Taxi to the Dark Side, Enron: The Smartest Guys in the Room) tries to get his arms around WikiLeaks, the online clearinghouse for whistleblowers, but the personalities are so various and the issues so complex that his movie lacks a center. The most obvious protagonist is WikiLeaks founder Julian Assange, and Gibney dutifully recounts the allegations of sexual assault in Sweden that have dogged him, but this story never progresses far beyond the savior/satan duality that prevailed in the news media. More pertinent to the political impact of WikiLeaks is Bradley Manning, the U.S. soldier accused of having leaked classified material on the Afghanistan war; in this case Gibney has little to work with visually except E-mail texts, yet the sequence in which Manning confides in former hacker Adrian Lamo and gets turned in to the FBI supplies the kind of human drama that has made Gibney’s work so engrossing in the past.
