Public Enemies Universal Pictures Description

The following is Universal Pictures promotional copy for Public Enemies, which is slated for release July 1st, 2009. The trailer was expected to be shown by the end of this December, but so far it hasn't been featured on Universal's site. Another July film trailer has been posted, so it makes me wonder whether Michael Mann is still pondering on how best to edit his short trailer to gain as wider audience as possible and convey not just the story of the film, but the potential depth of it beyond its realistic shoot outs. Michael Mann has historically found it difficult condensing the broad landscapes of his movies into "in-a-nutshell" trailers. Here is Universal's write up about the story of Public Enemies:

In the action-thriller Public Enemies, acclaimed filmmaker Michael Mann directs Johnny Depp, Christian Bale and Academy Award® winner Marion Cotillard in the incredible and true story of legendary Depression-era bank robber John Dillinger (Depp)—the charismatic bank robber whose lightning raids made him the number one target of J. Edgar Hoover’s fledgling FBI and its top agent, Melvin Purvis (Bale), and a folk hero to much of the downtrodden public.
No one could stop Dillinger. No jail could hold him. His charm and audacious jailbreaks endeared him to almost everyone—from his girlfriend Billie Frechette (Cotillard) to an American public who had no sympathy for the banks that had plunged the country into the Depression.
But while the adventures of Dillinger's gang—later including the sociopathic Baby Face Nelson (Stephen Graham)—thrilled many, Hoover (Billy Crudup) hit on the idea of exploiting the outlaw's capture as a way to elevate his Bureau of Investigation into the national police force that became the FBI. He made Dillinger America's first Public Enemy Number One.
Hoover sent in Purvis, the dashing "Clark Gable of the FBI". However, Dillinger and his gang outwitted and outgunned Purvis' men in wild chases and shootouts. Only after importing a crew of Western ex-lawmen (newly baptized as agents) who were real gunfighters and orchestrating epic betrayals—from the infamous "Lady in Red" to the Chicago crime boss Frank Nitti—were Purvis and the FBI able to close in on Dillinger.
