Christopher Nolan will actually begin shooting The Dark Knight Rises on location in Pittsburgh and other assorted locales by this summer. Before production can get underway however, there are still some loose ends that need to be tied up in the area of casting for the concluding chapter in Nolan’s Batman trilogy.

One such bit of casting concerns Nestor Carbonell, who is actively negotiating to reprise his role as Gotham Mayor Anthony Garcia in The Dark Knight Rises.

Carbonell famously appeared to have worn eyeliner for his part as Mayor Garcia in The Dark Knight, though it was eventually revealed to just be his natural look – and not a reference to the drawing style of Frank Miller’s The Dark Knight Returns. Variety has confirmed that Carbonell is likely to return for Nolan’s final Batman picture – and will join actors like Daniel Sunjata and Josh Pence as another important supporting player in the film.

With so many noteworthy thespians signing on for The Dark Knight Rises of late, there seems to be some confusion about the significance of their parts in the film – so here is a rundown of the cast members and their respective roles in the pic:

  • Christian Bale – Bruce Wayne/Batman
  • Gary Oldman – Commissioner Jim Gordon
  • Michael Caine – Alfred
  • Morgan Freeman – Lucius Fox
  • Anne Hathaway – Selina Kyle
  • Tom Hardy – Bane
  • Joseph Gordon-Levitt – Alberto Falcone?
  • Juno Temple – “a street-smart Gotham gal”
  • Josh Pence – Young Ra’s Al Ghul
  • Diego Klattenhoff – Rookie Cop
  • Daniel Sunjata – Special Forces Operative
  • Burn Gorman – ??? (supporting role)
  • Marion Cotillard – Talia Al Ghul?

Recent rumors about Dark Knight Rises featuring a third major villain from Batman’s rogue gallery or how the League of Shadows could fit into the picture aside, no one outside of Nolan and his crew possess any concrete knowledge about what will go down in the Caped Crusader’s next movie. We’ll get some answers soon enough – but, for now, feel free to speculate about how all these puzzle pieces fit together, as you will.

The Dark Knight Rises in theaters on July 20th, 2012.
