With a low-key yet intensely charismatic Johnny Depp as its lead, you could describe Michael Mann's Public Enemies as the story behind the criminal activity of the infamous, Depression-era bank robber John Dillinger. But that's not entirely accurate. The film is also about the nascent, frequently misguided authority of the FBI, personified here by a stalwart agent (a somber, less-throaty-than-usual Christian Bale) and showboating chief J. Edgar Hoover (a spectacular Billy Crudup). It's also about early media saturation in our country, and the public's complicity in turning villains into heroes, and the labyrinthine hierarchies among American gangsters, and - as embodied by a dazzlingly desirable and powerful Marion Cotillard - the ever-unpredictable nature of love. And, more than anything, it's about the exquisite craftsmanship of Michael Mann, whose Public Enemies doesn't look or sound quite like any other crime movie you've seen, and whose technical virtuosity might make Public Enemies impossible to forget.
