Johnny Depp and Christian Bale are on opposite sides of the law in Michael Mann’s ’30s gangster flick.

Michael Mann is a born and bred Chicagoan, so it makes sense he’d one day get around to chronicling the Windy City’s gangster days, when crooks with colorful names like Pretty Boy Floyd and Baby Face Nelson roamed the streets, trading gunfire with the coppers and spending their ill-gotten cash on drinks and dames.  This era was previously chronicled in Brian De Palma’s beloved The Untouchables, written by another Chicago native David Mamet and starring Kevin Costner as lawman Eliot Ness and Robert De Niro as crimelord Al Capone.  Set after Capone’s capture, Public Enemies follows FBI agent Melvin Purvis (Christian Bale) as he attempts to capture charismatic bank robber John Dillinger (Johnny Depp).  The rest of the cast includes Marion Cotillard as Dillinger’s girlfriend, Billy Crudup as J. Edgar Hoover and Channing Tatum as Pretty Boy Floyd.  But the match-up we can’t wait to see is Batman vs. Captain Jack Sparrow…
