| > First off, what happens to the Joker? We see him getting arrested, but he had no problem escaping from jail earlier and he even tells Batman that they'll continue fighting until one of them kills the other.|
I doubt the police will treat him as lightly as they did before. Plus, I don't think he expected to be caught at that point, so I doubt that he has a plan to escape right off the bat.
| >I think it'd be a terrible idea to have a new actor play him in the sequel, not to mention disrespectful to Heath Ledger's memory, so why does the movie imply that he'll be back?|
The movie ends the way it does because they finished filming before Ledger died, so they couldn't very well change it now.
| >Also, is Harvey Dent supposed to be dead, or will he be returning too? The fall he took didn't seem that bad, and Batman suffered no injuries at all from it. |
Why would they have a memorial service for Dent if he was still alive? The ending gave every indication that he was dead without outright saying it.
| >If he did die, it'd mean Batman finally killed someone, which completely goes against the theme of both movies. But if he didn't, how can Gordon possibly cover up his crimes if he's still alive and clearly insane?|
Batman tackled him to prevent him from shooting someone else, Dent's death was an unfortunate side effect.
| > Also, Gordon says that Dent killed five people, but I only recall him shooting the old man and the limo driver. I guess Maroni could've died in the crash, but it doesn't seem likely if Dent could survive it with half his skin gone. And who was that old man anyway, what role did he have in Rachel's death?|
There did seem to be some discrepancies in Two-Face's body count. Gordon also said that they had two dead cops, but the girl lived, so I'm guessing that there were some off screen coin tosses. As to the old man, he was a dirty cop that handed him (Dent) over to the mob.
| > Finally, what was up with that scene where Batman and Rachel fall from a skyscraper onto a cab and get up just fine? Did I miss something where Batman did something to slow his fall, or did he somehow survive a 50+ story fall just by being Batman?|
He extended half of his cape. The cape that he's been using as a glider in both movies. Also, they didn't die because Batman took the majority of the crash and his body armor absorbed most of the resulting shock.
