Adaptational Wimp: John Reid is somewhat less of a badass compared to his radio and TV versions. Justified as most versions of him are a Texas Ranger before donning the mask while this one is a City Mouse lawyer.
Audience Surrogate: The boy in the Lone Ranger costume that is listening to an aged Tonto tell the story.
Badass Damsel: While she ultimately needs the Lone Ranger to save her, Rebecca Reid is not helpless. She knows how to handle a gun, refuses to be cowed by her captors, and repeatedly attempts to rescue herself. She even climbs on the outside of a moving train at several points.
Bottomless Magazines: Particularly during the climax. They're using six-shooters while fighting on top of trains, riding horses etc, and we never see a single one of them reload until the climax. Before that point many of the smaller action sequences averted the trope, notably a double-barreled shotgun with only 2 shots per load.
Bunny-Ears Lawyer: Tonto is seen as this by his fellow Comanches due to his strange costume and dead-crow headdress, which have no basis in historical Comanche clothing.
Butt Monkey: The Lone Ranger himself throughout a massive portion of the film, until he finally becomes the Badass we know and love.
By-the-Book Cop: John Reid starts out as a By The Book Prosecutor (The Book in this case being John Locke's Two Treatises On Government), going so far as to insist on taking Tonto back into custody after he saves his life and helps him escape from a derailed train. His struggle through the film with whether To Be Lawful or Goodinevitably turns him into a Cowboy Cop (ha!), albeit a scrupulously moral one.
Cavalry Officer: He and his regiment are called in to take care of the Comanche thinking they broke the treaty and raided settlements. He later joins forces with the villains after learning he spilled innocent blood.
Chained Heat: John Reid and Tonto spend their first fight against Cavendish shackled together.
Character Tics: Cole has a distinctive way of twirling his pocketwatch, which Tonto can be seen trying to emulate before he's apparently even met the man. This hints at the fact that they've met before; Cole being the man who gave Tonto the watch when he was a child in response for being guided to a silver prospect, shortly before wiping out Tonto's entire tribe.
Failure Hero: The Lone Ranger may kill the bad guy, but he utterly failed to save the Comanches from being massacred.
False Flag Operation: Butch Cavendish and his gang disguise themselves as Comanches and attack white settlements in order to make it look like the Comanche have violated the treaty.
Family-Unfriendly Death: The Lone Ranger's brother has his heart cut out and eaten by Cavendish. It's a Sound-Only Death as all we can see is John's horrified Reaction Shot, and the audience only have their imaginations and the earlier rumors of Cavendish's cannibalism to guess what's happening.
Tonto says silver made Cavendish, and it would kill him. While this seems to be foreshadowing the silver bullet, it's ultimately how Cole meets his end; crushed under the very silver he spent all this time mining that made him and Cavendish the people they are. Though that silver bullet does end up saving Tonto's life.
Also a hint that the story being told about the kid who got his tribe killed was indeed Tonto.
The fact the chief mentions two white men that Tonto lead to the silver.
when you first see Cole, he flips his pocket watch before reading it. You later see that watch flip again during the story of Tonto's backstory. It's not only your first clue to who one of those men are, but it also hints slightly later at Cole's connection to Cavendish.
The first thing seen in the film is a half-finished Golden Gate Bridge, which is a large nod to how the story ends.
Framing Device: A young boy listens to the story of the Lone Ranger being told by an aged Tonto.
Gatling Good: The original models used by the U.S. Calvary to kill the charging Comanches.
Go-Go Enslavement: A maid dresses Rebecca in a fancy black gown and lipstick after she and Danny are "rescued" by Cole, who intends to marry her so that her son can become his heir. Based on her reaction to seeing the lipstick on her wine glass, she is not comfortable in the outfit.
I Have You Now, My Pretty: Both Cavendish and Cole pull this on Rebecca, though in Cole's case nothing can actually happen, since he's implied to be a eunuch. His real reason for wanting to marry her is because she has a son that he can leave his railroad empire to.
I'm a Humanitarian: Butch Cavendish who eats the hearts of his victims. He does this to the title character's brother. Probably another reason Tonto thinks he's a Wendigo.
Improbable Aiming Skills: The first time it's purely an accident, but for the second example John makes an impossible shot across a ravine, from one moving train to another, to blast a gun out of another man's hand.
Also, during the first flashback, he shoots a bottle of something or other out of a man's hand. From a moving horse.
Instant Knots: During his final fight with Cavendish, the Lone Ranger wraps his whip around a tree and uses it to get yanked off the runaway railway car.
Dan uses this to pull Frank off the roof of the railway car.
It Makes Sense in Context: That bank robbery committed by the Ranger and Tonto at the start? They did it to get some of the materials they needed to foil Cole's Evil Plan.
I've Come Too Far: The reason the captain leading the American forces joins the villains; by the time he finds out what's going on, he's already killed too many innocent Native Americans and would be held responsible for their deaths.
When Rebecca is pushed off the roof of the train by Cavendish, she lands in the saddle of Silver who is galloping along beside the train.
Leg Cannon: Red has a shotgun built into her ivory artificial leg.
Magical Native American: Tonto has elements of this, in his manner of dress, his plot exposition, and his presenting himself as a Scarily Competent Tracker who Speaks Fluent Animal. Subverted later on when John meets the rest of the Comanche, who inform him that Tonto is insane and the Native American myths that he's been reciting throughout the film are considered by the rest of them to be just that, myths; his skills as a tracker are also revealed to be fairly hopeless.
Man Child: John accuses Tonto of being this after hearing his back story from the Comanche tribe. While arguing the pros and cons of killing Cavendish and proceeding to insult one another John accuses of Tonto of being "a screwed up little kid" who never learned how to live with the guilt of getting his entire tribe wiped out by telling the films villains where the silver mine was.
Tonto also believes Cavendish isn't an ordinary criminal, but a Wendigo. This is the explanation for why the Lone Ranger uses silver bullets. Cavendish being a cannibal doesn't help things...
The Lone Ranger not only gets a psychic vision from picking up a piece of Cavendish's silver, but despite not having fired a gun in eight years prior to his "death", he manages to repeatedly pull off ridiculous trick shots. He finally just goes with it.
Misplaced Wildlife: The vultures seen briefly in the film are African Griffin Vultures, not Turkey Vultures as would be more appropriate for the setting. This is an especially odd case, considering how iconic, and readily obtainable real Turkey Vultures are.
The movie follows up a scene where Butch Cavendish cuts out a man's heart and eating it with a slapstick comedy scene involving horse excrement. Also, the brutally violent gunfights alternate with almost comic book-ish stunt sequences.
Even worse is Tonto's farcical jailbreak of the Lone Ranger segueing immediately into a blood-drenched no-quarter battle between the Comanche and US Cavalry before their eyes.
My God, What Have I Done?: The Captain suffers two of them. The first one is when he realizes he was duped into leading his men to killing innocent Native Americans... but subverted when he's talked into burying the whole thing in denial. The second one comes after he stabs the Comanche Chief and sees his blood on his hands, calling back to the Big Bad claiming he had blood on his hands from the first incident.
Not So Different: Cavendish pretty much says this word for word when He discovers the Ranger is actually John. He says they're both men that have to wear masks, implying that he's had to maintain the secrecy of things he's done.
Outrun the Fireball: Butch throws kerosene and dynamite down a tunnel, and our heroes must outrun the result.
Prase Catcher: When people see the Lone Ranger they ask, "What's with the mask?"
Running Gag: Men just can't resist the urge to touch Red's ivory prosthetic leg.
Tonto's "trades", which always seem to work out in his favor.
Sadly Mythtaken: The Wendigo is identified as a Comanche myth, but it is actually Algonquian, who were prominent in what is now the northern US and Canada, and the Atlantic coast - it's indicative of long winters and desperation.
The Good, the Bad and the Ugly inspires Tonto looting the corpses of Dan's posse, he and John riding through the desert with an umbrella and the bridge detonation.
Once Upon a Time in the West gets quite a workout: the railroad plot, the intro of Dan and his posse wearing dusters, the squeaky windmill featuring in one scene, and Tonto revealing his past identity to Cole "at the point of dying." Hans Zimmer's music sounds like a conscious homage to Ennio Morricone, too.
Butch Cassidy and the Sundance Kid inspires the standoff between John, Tonto and two of Butch's henchmen, with the heroes arguing over who should kill whom, and John admitting he's not fired a gun in years.
The train robbery features one of Butch's men forcing hostages to sing "Shall We Gather at the River?", in a nod to The Wild Bunch.
The Comanche scenes, flashbacks to the massacre in Tonto's backstory and the line "it's a good day to die" all originate from Little Big Man.
At one point, the Big Bad tells Tonto "Pretty soon no one will even know you people were here." A very similar line popped up in the director's previous film Rango.
Shovel Strike: When Tonto is about to finish off Butch, Reid knocks him out with a shovel to do things by the book and let the court handle things.
Show Some Leg: Red manages to do this with her ivory leg to distract the Captain at Promontory Point.
Sibling Triangle: Implied with Dan and John with Rebecca before John left to learn law. Dan married Rebecca and have a son, Danny Reid (Jr.). It is implied that Dan knows John and Rebecca still loves each other.
Silver Bullet: Tonto made one for the Lone Ranger to shoot the Wendigo.
Thou Shall Not Kill: As in the original series, the Lone Ranger wants the justice system to deal with the villains rather than take revenge himself, and enforces this trope on Tonto, despite the fact Tonto wants vengeance on Cavendish and Cole. In the end, Tonto passes up killing Cole... but has no qualms about leaving Cole to his Karmic Death. Ironically, Reid's first attempt at A-Team Firingends up killing the bad guys even more gruesomely than a gunshot would have done.
Thrown from the Zeppelin: When Cole announces his hostile takeover of the railway, the chairman of the board strenuously objects. Cole shoots him in the back, and asks who the other shareholders think should be the next chairman... However, the guy shows up later with Just A Flesh Wound.
Tonto Talk: Yup. The Comanche chief speaks English somewhat more fluently, though.
Unhand Them, Villain!: Butch Cavendish grabs Rebecca as a hostage during the final battle. When the Ranger orders him to let her go, Cavendish threatens to drop her off the side of the moving train. Subverted when the Ranger tells him to do it as she always seems to land on her feet.
Well-Intentioned Extremist: Latham Cole seems to genuinely believe he's doing the right thing with his actions. Cavendish? Not so much.
Wendigo: What Tonto believes that Butch Cavendish is. Understandable, as he has a habit of eating human flesh.
What Happened to the Mouse?: Cole is the only villain who dies on-screen. Cavendish takes a speeding train to the face off-screen, so unless he really was a Wendigo (or at least Robert Carlyle's character from Ravenous) it's pretty safe to assume he's dead too. However, Captain Fuller is last seen jumping from said train into the woods (a feat repeatedly shown to be survivable in the film), and is never seen or mentioned again.
