A Rede Social

This is a film which simply shouldn't work, but it does - magnificently. A story centred on a teenager who becomes the world's youngest billionaire, a web site that reaches a million users in two years, and a cast of real life characters with names like Zuckerberg and Winklevoss just shouldn't be possible. A convoluted tale of raw conflict on the origins of a new type of web site should not lend itself to an expensive movie as opposed to a television documentary. It succeeds because it is not about the technology but about creativity and conflict and about friendship and betrayal. It succeeds because of a magical combination of accomplished direction, scintillating dialogue and superb acting.

The direction comes from David Fincher who has had variable success, all the way from "Alien 3" to Se7en", but here he is right on form with a flashy, but tightly structured, presentation that never fails to command your attention and interest. The all-important, sparkling script is courtesy of Aaron Sorkin who gave us "The West Wing" - the best television series ever - and yet apparently does not do social networking.

At the heart of the movie is a brilliant, Oscar-worthy performance from Jesse Eisenberg as the 19 year old Harvard student Mark Zuckerberg, the genius behind "The Facebook" (the social network), the unsympathetic anti-hero of the adventure, a borderline sociopath variously described by women characters as "an asshole" and someone "just trying so hard to be" one. Andrew Garfield is excellent as Zuckerberg's Harvard roommate and co-founder of the site Eduardo Savarin; thanks to the wonders of CGI, Arnie Hammer manages to be terrific as both the twins Cameron and Tyler Winklevoss; while singer Justin Timberlake is a revelation as the Napster founder Sean Parker. This is a testosterone-charged fable with room for women only in minor support roles - ironic in that getting girls was the impetus for the Facebook project.

The film opens in 2003 with a breathlessly wordy encounter and closes in 2009 with a poignantly wordless scene. In between, the story zips along at the frenetic pace characterised by the business itself. Adapted from Ben Mezrich's book "The Accidental Millionaires", the framework for the fascinating narrative is not one but two courtroom dramas or, to be more accurate, pre-trial hearings (both resulted in out-of-court settlements which tells you a lot). Clearly you shouldn't judge a book by its cover.
