Sure, Johnny Depp looks dashing as John Dillinger. Christian Bale makes a mighty fine lawman. And no one will deny the delicious sex appeal of Marion Cotillard. But the real star of the movie "Public Enemies," which opened Wednesday in wide release, is the brawling, bustling and undeniably beautiful city of Chicago. The film's director, Michael Mann, is a hometown boy who grew up in Humboldt Park and graduated from Amundsen High School. Obsessive about historical accuracy and a stickler for even the smallest details, Mann shot in Chicago for a total of 36 days last year, sending scouts to many of Dillinger's old haunts and filming, in some cases, on the very streets the bank robber once prowled. - Peter Stinson
