Sacha Baron Cohen's next film The Dictator is currently shooting in New York City.  For those who don't know, Cohen plays "a heroic story of a dictator who risked his life to ensure that democracy would never come to the country he so lovingly oppressed."  The film is inspired by the novel, Zabibah and The King, by Saddam Hussein.  The set photos we've seen so far make it look as nutty as Cohen's previous films.  We have now learned of a new cameo in the film as well as how much a previously-announced actor will be in the film.Hit the jump for more details.  The film, directed by Larry Charles (Borat) also stars Anna Faris, Ben Kingsley, J.B. Smoove, John C. Reilly, and Megan Fox.  The Dictator opens May 11, 2012.We've found out that Fox is shooting her role today and that she'll only be shooting for one day, which makes it sound like it's a cameo performance as opposed to a serious supporting role.  We have also learned that all of the supporting roles will be played by name actors, and while we've already heard about folks like Ben Kingsley and John C. Reilly, you can now add The Office's B.J. Novak to the list.  Obviously he's not as big as Reilly or Kingsley, but it's yet another sign that unlike Borat and Bruno, The Dictator won't be Cohen and a cast of unknowns.  However, the film is also scripted which helps to explain the large influx of supporting actors.
