Today, we've been sent three very interesting rumors concerning Christopher Nolan's The Dark Knight Rises.  Before we go into what we were sent, it's important to know that Nolan's intense desire for secrecy regarding his films makes it impossible to get confirmation or denial on any rumor.  There will be no official word on The Dark Knight Rises until Nolan says so.  However, we believe there is some veracity to the information we've been sent and thought we would pass it along to you.First up, a source tells us that Eva Green and Naomi Watts are going to be cast in the film.  The source doesn't know which roles they're playing, but believes it's Talia al Ghul and Vicki Vale, respectively.  However, we have no confirmation these characters are even in the movie.  We previously reported that the film would have two new female leads: a love interest and a villain.  Vicky Vale, a reporter who was played by Kim Basinger in Tim Burton's Batman, would presumably be the love interest, while Talia al Ghul is the daughter of Ra's al Ghul (played by Liam Neeson in Batman Begins) and in the comics has been an anti-hero/love-interest for Batman.  Hit the jump for more rumors regarding The Dark Knight Rises, which is set to be released on July 20, 2012. [Update: Heat Vision is reporting that Keira Knightley, Anne Hathaway, Jessica Biel, Kate Mara, Charlotte Riley, and possibly Gemma Arterton are testing for the female roles, so it's possible that Green and Watts haven't been cast.  However, we have independently confirmed that Talia al Ghul is in the movie.]Before moving on to the other rumors, it's worth noting that Watts' name was mentioned before as a possible contender to play one of the female leads.  Green's name is new to the mix, but she's age-appropriate in relation to Christian Bale, she's sexy as hell, and would nail the femme fatale angle of Talia al Ghul or even Catwoman if that's the film's female villain.  Again, we cannot confirm or deny this casting, but we wanted to pass it along.The same source also tells us that principal photography is set to begin on May 6th with post-production set to begin on November 28th.  This timeline coincides with an earlier report from Michael Caine who said that filming was supposed to run from May through November.  Finally, this source tells us that the leaked script for the film that recently hit the net is fake and that the cast will get the real script sometime next week.A different source tells us some new details regarding the design of the new Batmobile and Batcave.  It's not surprising that both will be in the new movie since the old Batmobile was destroyed in The Dark Knight and Bruce and Alfred have been working on the Batcave since the end of Batman Begins.  Our source "Raphael" tells us that the new Batmobile (aka The Tumbler) has been redesigned as a sleeker version, but still powerful and with all the gadgets.  As for the Batcave, it will be the same cave we saw in Batman Begins and they're attempting to keep the classic stuff like the circular bay for the Batmobile, but keep the look modern.  They're also setting up the Batcomputer and storage for the Batsuits.  And if there's a new Batmobile and a new Batcave, is it possible we'll be getting a new Batsuit in The Dark Knight Rises? (Hint, hint.)Again, this is all rumor because we can't get it confirmed.  However, we trust these sources enough that we're willing to post the information they've sent us.  More as we hear it.
