The Dark knight Rises de Christopher Nolan : Tom Hardy est Bane! Anne Hataway est catwoman!

Story begins with Batman on the run from the law after the events towards the end of TDK. The mayor orders Gordon to form a task force with the sole purpose of finding and arresting Batman. Gordon selects Lt. Harvey Bullock to head the operation, because Gordon knows Bullock is incompetent and will not succeed. (Bullock is a small role similar to Flass in Begins) Gordon's main purpose in life is to rid Gotham of corruption and to clear Batman's name.
Meanwhile the Maroni and Falcone families are at war with each other, and Batman still disrupts there business. Alberto Falcone (small part), son of Carmine, is now the head of the family and requests help from his childhood friend and financial backer, Roman Sionis (major part). Sionis is one of the wealthiest business men in the world, and has a strong taste for violence. Through his infinite wealth and connections he hires an assassin to wipe out everyone in the Maroni family and kill Batman. This assassin is Floyd Lawton.(major part, Hardy. character is described as having the skills of Leon and personality of Stansfield from "The Professional")
In the backdrop of all this a serial killer has been killing people and burning down buildings in the Narrows (New Orleans set), the killer is suspected to be Zsasz, but it is not confirmed. Gordon cannot gain support from the mayor or anyone to put his best men in the Narrows. (We find out later that the mayor is corrupt and encourages violence in the Narrows) Gordon then tries to persuade Batman to find out who is behind the carnage in the Narrows. We later find out that its a group of men wearing different masks, called the False Facers led by Roman Sionis. (This is where we see him as Black Mask, there are a few characters with minor parts in the group, one of which is Waylon Jones who wears a green crocodile mask and is the brute of the group, there may be a few others from the comics). The motive of the False Facers is to completely drive down the value of property in the Narrows so that it can be bought by Sionis and others from Gotham's Elite at pennies on the dollar.
Sionis is also a major business rival to Bruce Wayne and continues to lose financial ground to Wayne Enterprises. As a result he sends a desperate employee, Selina Kyle (major part), to go work for Wayne Enterprises and seduce Bruce to uncover any information possible to gain an advantage on Wayne's company. Sionis threatens to kill Selina's family who lives in the Narrows if she does not do this.
While working there Selina uncovers some of Batmans old equipment to which she steals and conforms it for her use. She does not suspect Bruce of being Batman at this time only that Batman gets his equipment from Wayne Enterprises. She later becomes and integral part in the False Facers'/Narrows storyline. The Narrow's residents nickname her the Catwoman. Selina and Bruce also form a romantic relationship during her employment and later confesses Sionis' plan to Bruce. Sionis then begins to kidnap board members of Wayne Enterprises including Fox. Coleman Reese is kidnapped and confesses to Sionis that Bruce is Batman, Reese is eventually killed by Sionis. This is when Bruce finds himself being a target and begins to spend more time as Batman than he does as Bruce.

There are some storylines that are highlighted in the movie. One of which is how two men, Bruce and Roman, from similar childhoods can be so opposite as adults. Another is how two people, Bruce and Selina, from opposite childhoods can be so similar as adults.
I am told that they are not sure how Hardy's character will be referred to in the movie. I think they are leaning towards just calling him Floyd, instead of his full name or his nickname; Deadshot.
As far as screen time goes expect Hardy to be on screen as much as Harvey/Two Face, Sionis as much as Joker, Selina as much as Rachel in Begins and Bullock as much as Flass in Begins. Waylon Jones character is about as big a part as The Chechen in TDK. Alberto Falcone's part is pretty small as well.
I know they are aiming for a big name for Sionis, someone who can be similar to a Bruce Wayne, but be able to turn into a John Doe (Seven) type killer. I think Matt Damon may be the guy here. Dicaprio will not play a lesser role than Christian Bale.
Hardy's character will have some amazing action sequences with Batman and Gordon. And there will be some intense scenes between Bale and whoever plays Roman. Selina Kyle may be a fresh new face. Olivia Wilde has been mentioned, depending on her performance in Tron.
Nolan wanted this to be called "The Batman" but WB wanted "The Dark Knight " in the title somehow. TDK Returns was considered but Nolan and WB opted to keep that for a later use.
