Batman Villians?

Especially his magic trick, and the nurse thing. Hah.

What about the third installment's villains?

Two-Face. It was widely believed that Two-Face would be the villain of the third installment. David Goyer, who penned Batman Begins and helped on The Dark Knight, had said that the Joker would disfigure Harvey Dent, aka Two-Face, in the third film. But we now know that Dent's disfigurement occurs in Dark Knight. And, of course, he dies at the end. (There is speculation on how and why he might still be alive. See: this FAQ entry.)

The Joker. Asked about whether the Joker would appear again (which would require the role to be recast), Christopher Nolan said, "I don't know. I honestly have not taken a moment away from what is going on with the film now to even think about that. I don't know. I simply don't know." [source needed] It has been rumored by an unconfirmed source that there is some extra footage of Heath Ledger's Joker that can be used in the next sequel.

The Riddler. In an interview with Movie Hole, Gary Oldman said, "Maybe we don't need the Joker. Because we'll have The Riddler."

There has been speculation on the web that that either Coleman Reese (or Mister Reese - "Mysteries", played by Joshua Harto) or Mike Engel (played by Anthony Michael Hall) might turn into the Riddler, although neither character has the traditional origin or the characteristics of the comic books' Riddler. In most incarnations, his name is Edward Nigma (E. Nigma).

In one of the newspapers released with the viral marketing, there is a 'letter to the editor' that is authored by Edward Nashton, a common alias of the Riddler.

The Catwoman. There is one point where Lucius Fox and Batman are discussing the new Bat-suit. Batman makes a comment about the strength of the suit, asking if it would be able to protect him from large dogs. Lucius says it should protect him from "cats"--a possible reference to Catwoman.

The Scarecrow. Some fans were disappointed about the Scarecrow's small role in the film. But he does survive the movie, which means he could return with a larger role in the third film.

The Black Mask. David Goyer has expressed a desire to use a villain that has not received previous film treatment. [source of statement needed] The news has put Roman Sionis/The Black Mask on the list of possibilities.

The Mad Hatter. There has been online speculation that Jervis Tetch (alias the Mad Hatter) makes a brief appearance in The Dark Knight, though this name is never used in the movie or in the credits. David Dastmalchian, who is supposedly playing Tetch, is simply billed as "Joker's thug."

The Penguin. Christopher Nolan has said that the Penguin is too "campy" a character for use in the reinvented Batman series. [source of statement needed]

The Calculator. During Rachel's interrogation of Lau, he makes numerous references to his "calculations being accurate." There is a DC villain that originated in early Batman runs known as The Calculator, who began as a campy low-level villain (complete with an over-the-top outfit), only to ditch the costume and lurk behind the scenes. In recent years, and in pivotal DC storylines, The Calculator is an integral part of the criminal underworld, particularly involved in financing criminals and providing information to the world's supervillains. This could be plausible, although Lau is seemingly burned alive as the Joker lights the large pyramid of cash on fire.

Talia Ghul. The daughter of Ra's Al Ghul could seek revenge on Batman for killing her father or perhaps try and carry out his plan for destroying Gotham.

Ra's Al Ghul. Henri Ducard, whom we discover is actually Ra's Al Ghul in Batman Begins, is killed in the train crash at the end of the film. Ra's Al Ghul is an immortal in the comic books. While Nolan's series seems to shun the supernatural, there's no reason that a new villain, believing himself to be the reincarnation of Ra's Al Ghul, couldn't arrive on the scene.

Harley Quinn. She is the psychiatrist who works at Arkham Asylum and tries to treat the Joker; but she winds up falling in love with him and becoming his girlfriend/sidekick. If the Joker returns (played by a different actor), she is a strong contender.

Poison Ivy. She may be too unrealistic for this series. But her origin and abilities can always be altered.

Mr. Freeze. See Poison Ivy.

Sal Maroni. It is believed that if Dent survived the car wreck in The Dark Knight, then Maroni could have as well.
