Falcone's Hannibal Lecture/"The Reason You Suck" Speech is one for the villainous - he has Bruce speechless, because Bruce knows Falcone's got him dead to rights. Which inspires him to walk the earth and eventually become Batman, leading to Falcone's very satisfying comeuppance detailed below.
Falcone: Look around you. You'll see two councilmen, a union official, couple off-duty cops, and a judge. Now, I wouldn't have a second's hesitation of blowing your head off right here and right now in front of them. That's power you can't buy. That's the power of fear....You think you've got nothing to lose. But you haven't thought it through. You haven't thought about your lady friend, down at the D.A.'s office. You haven't thought about your old butler.Bang!...People from your world...havesomuch to lose. Now you think, because your mommy and your daddy got shot, you know about the ugly side of life, but you don't. You've never tasted desperate. You're, uh, you're Bruce Wayne, the Prince of Gotham! You'd have to go a thousand miles to meet someone who didn't know your name. So, don't - don't come down here with your anger, trying to prove something to yourself! This is a world you'll never understand, and you always fear what you don't understand.
From the beginning: Bruce getting attacked in the food line, which results in this exchange.
Chinese Prisoner: You are in hell, little man! And I am the devil.
Bruce Wayne: You're not the devil. You're practice.
And so begins a beatdown of epic proportions, not just of the guy that attacked him, but every other prisoner that joins the fight. He even breaks a guy's leg!
Capped off by this funny/awesome moment when the guards come and drag Bruce away to solitary confinement for "protection":
Bruce: I don't need protection!
Guard: Protection for them! [cue a shot of the prisoners rolling about in the yard, screaming in pain]
"Actually, there were seven of them."
"I counted six, Mr. Wayne."
Ra's' line "If someone stands in the way of true justice, you simply walk up behind them...and stab them in the heart", said in a calm, cold voice. Made even better as it foreshadows the attacker coming up behind Bruce, which turns out to have been a feint for Ra's making an attack himself!
To keep the SWAT team occupied, Batman summons... a massive swarm of bats.
The scene was originally taken from the comic Batman: Year One, and was itself just the capper on an entire Moment of Awesome sequence.
Ducard: (failing to notice that Bruce had slashed several ninja with identical wounds) You cannot leave any sign.
Wayne: (early version of Batman growl) I haven't.
His escape. If Bruce Wayne wants to exit the house and catch some air he won't stop for a piddling obstacle like the entire League.
To elaborate, the false Ra's al Ghul tells Bruce to kill this one criminal to affirm his status as member of the League of Shadows. Owing to his one rulebefore becoming Batman, Bruce basically says "hell no", dips his sword into the hot coal and tosses it into some bags, beginning to burn down the temple. The League, in response, immediately ready their swords in unison, with Ra's doing the same and fighting Bruce as the temple explodes and collapses around them. Ra's ends up dying from having burning logs collapsing on top of him. The next thing Bruce does is to pick up Ducard and get the hell out of the house, but end up flying out as Ducard slides off the mountain. Bruce follows suit, and ultimately saves Ducard via using the spiked blades on his arm, proving that they can do more than just following the Rule of Cool.
The scene with Falcone loading a shotgun in his car, where you can just imagine his panic. He then whispers "What the hell are you?" Cue a smash of glass and say it with us now..."I'm Batman!"
One for a villain - Jonathan Crane is trying to destroy some evidence, when both of his mooks are taken out by an unseen assailant, who then reveals himself as the guy who singlehandedly took down a mob boss. So does he flee? No! He quickly slips on his mask, releases his fear gas, and then sets Batman on fire!
The moment where Batman first appears in Batman Begins is not just one of the most Crowning Moments of Awesome in the character's history, but possibly the greatest moment in motion picture history ever. Not only does he manage to dispatch an entire crew of mobsters single-handedly and reduce their boss from an arrogant, bullying invincible crime-lord to a terrified old man cowering in the back of a limo with a gun (which Batman then proceeds to pull the crime-lord out of through the sun-roof), he politely compliments an old homeless man on his coat (which Batman, years ago, gave to him) in the process. Oh, and he ties the mob boss to a spotlight, inventing the bat signal.
That intro moment in that sequence was with the long-haired guy with the sub-machinegun:
Mook:(blasting away with gun) WHERE ARE YOOOUU? Batman:(hanging upside down, coming into shot as we pan with the goon)Here. Mook: Yaaahh— (cut off as the black cape envelopes him)
The introduction of the bat-signal in approximately the middle of the movie. Jim Gordon shows up with a bunch of other police officers to the place where a group of Falcone's goons were. Another officer asked if they were Falcone's men, Gordon cynically remarked "does it matter? We'll never tie him to it anyway." Said officer responded "I wouldn't be too sure of that" and then nodded his head towards something that Gordon apparently didn't even notice beforehand; a searchlight pointed at the clouds, with Falcone chained to it such that his shadow formed a bat-silhouette in said clouds. It was a symbol of hope in a city that clearly needed it. It also helps that the music used in that scene has the same melody as was used earlier in part of "The Will To Act."
After snatching corrupt cop Flass from the alley below, dangling him over it by his ankles and interrogating him after visibly working himself up into the scariest interrogator in the universe:
The car chase. It's one of the most epic car chases, when you consider what Batman uses to take out multiple police cars in spectacular fashion - lots of caltrops that puncture cruisers' tires, cannons that blow away barriers, and lots of quick maneuvers.
Ra's al Ghul's reappearance in Wayne Manor, complete with him setting the house alight, and the page quote for this.
Even Alfred gets at least one when he knocks out a League of Shadows goon: "I hope you're not a member of the fire brigade," whilst rushing into the burning Wayne Manor to save Bruce. And the subsequent "You still haven't given up on me" / "Never!" exchange.
And when he tries to help the pinned Bruce.
Alfred: What was the point of all those push-ups if you can't lift one bloody log?!
Loeb tells a desperate Gordon that "There's nobody left to send in!". Cue The Tumbler coming out of nowhere and jumping into the Narrows.
While protecting a little boy Rachel tasers Scarecrow. I repeat she TASERS the FREAKING SCARECROW. In the FACE. HOW is that NOT awesome?
To elaborate, Scarecrow, in that scene, is riding a horse. That breathes fire. And Rachel STILL tasers him in one shot.BAD. ASS!
Liam Neeson chanelling Qui-Gon Jinn as in his last moment, Ra's calmly faces his death-by-train.
Bruce Wayne confronting his fear of bats in the batcave definitely deserves mention.
And related, a three-sentence exchange that sums up the reason Batman choose such an icon for his identity.
Alfred: "Why bats, Master Wayne?" Bruce: "Bats frighten me. It's time my enemies shared my dread."
Cillian Murphy's magnificent performance as Dr. Jonathan Crane, aka, Scarecrow. Up until this point, Scarecrow was a loud, obvious villain - not that this made him any less frightening, mind you. But Cillian's good looks, calm demeanor, soft-spoken delivery and incredible acting managed to add a whole new side to Crane, and make him more unassuming, more subtle, and more effective as a villain. He's unsettling at first, and downright terrifying when he puts on his mask. No wonder Crane's an Ensemble Dark Horse now.
The final scene as Batman takes the "calling card" left behind by a thief and flips it over to reveal...a Joker.
The movie ultimately had a modest box office gross internationally, but generated enough good will and restored the cinematic Batman franchise well enough to greenlight a sequel that would become even more popular and break box office records.
Also doubly so for long-time Batman comic fans: instead of immediately bringing in the well-known villains from the previous films, Nolan and Goyer instead bring in other villains from the Batman lore that probably would not have been touched before: Ra's Al Ghul, the League of Shadows, Scarecrow and even Mr. Zsasz (in a small role).
