The official trailer for the Barry Levinson-directed film, which arrived Tuesday, shows the Academy Award winner in a dual role, in which he portrays two of New York's most notorious organized crime bosses, Frank Costello and Vito Genovese.

Robert De Niro is starring as the Mafia boss in a mob drama. Sounds about right. But this time, he’s playing both lead roles: Vito Genovese and Frank Costello. De Niro will double his acting expertise in The Alto Knights, a crime drama inspired by the true story behind Costello and Genovese’s deadly rivalry.

Jan. 14 (UPI) -- Warner Brothers is previewing The Alto Knights, starring Robert De Niro as both Frank Costello and Vito Genovese. The movie is about the power struggle between the iconic gangsters. The trailer shows the pair meeting in a dark restaurant in an apparent hotel.

That's the case in The Alto Knights, which reunites De Niro with director Barry Levinson. The pair had previously collaborated on films like political satire Wag the Dog and Bernie Madoff biopic The Wizard of Lies.

If one Robert De Niro wasn't enough, try two, as the Oscar winner plays dueling mob bosses in Barry Levinson's crime drama, The Alto Knights.The Latest Tech News, Delivered to Your Inbox
