Trumpkin the dwarf, despite having no belief whatsoever in Aslan, High King Peter, or Susan's horn, declares that he will take on the highly dangerous task of going to meet whatever help the horn calls up: "You are my King. I know the difference between giving advice and taking orders. You have my advice and now it's the time for orders."
Peter is essentially a series of CMoAs. Re-enter the High King of Narnia, who may be an English schoolboy but also happens to be a brilliant leader, seasoned warrior, excellent strategist and wise counsellor. Lewis gets extra points for showing exactly why Peter is the High King over all kings in Narnia without turning him into a Marty Stu.
Edmund gets some of this, too. Read the chapter where he turns up to give the challenge to Miraz. Glozelle and Sopespian notice him going to Miraz's tent and have brief swooning session over his aura of badassitude.
His battle cry deserves a mention as well:
"Narnia! Narnia! THE LION!"
The entire White Witch encounter was only in The Film of the Book. The hag and the Werewolf in the book only got as far as suggesting raising her. Why? Peter's and Edmund's Big Damn Heroes moment where they burst in just in time to stop the ritual from starting in pretty badass style.
The Werewolf's boast is a creepy moment of Awesome that was once the page quote for the Badass Boast page. It's even better in the book; rather than barely-contained rage, it's delivered in a darkly certain monotone that's chilling and deeply terrifying.
"I am hunger. I am thirst. Where I bite, I hold till I die, and even after death they must cut out my mouthful from my enemy's body and bury it with me. I can fast a hundred years and not die. I can lie a hundred nights on the ice and not freeze. I can drink a river of blood and not burst. Show me your enemies."
Not to mention the fact that both he and Susan are possibly out of practice-it's been a year since they've been in Narnia, after all, and skills like fencing and archery take a lot of constant practice to keep up. The fact that they can beat Trumpkin shows how good they must've been before they left.
Aslan roars to awaken the dryads (tree nymphs). And not just any roar, one that echos and carries across a huge distance and rolls across the plains like thunder. Done epically well in the radio drama.
Reepicheep at the end, defending his honor (or rather, defending his right to defend his honor) to Aslan himself.
Aslan: I have sometimes wondered, friend, whether you do not think too much about your honor.
Reepicheep: Highest of all High Kings, permit me to remind you that a very small size has been bestowed on us Mice, and if we did not guard our dignity, some (who weigh worth by inches) would allow themselves very unsuitable pleasantries at our expense.
His mice get one when he gets his tail cut off. Lucy heals him, but her cordial can't restore his severed tail. Whereupon the mice draw their swords to cut off their own tails, declaring that they will not retain an honor denied their leader. Which could also double as a Heartwarming Moment. Either way, Aslan is so pleased by their devotion that he gives Reepicheep his tail back.
Another Crowning Moment of Awesome/Heartwarming follows immediately as Aslan reveals that Reepicheep and his followers became Talking Mice when they nibbled the cords from his body in the previous book.
Aslan, the girls and the Old Narnians running around putting Narnia to rights while the battle is being won — the nicest, gentlest Roaring Rampage of Revenge ever (although it works best if you don't apply Fridge Logic to questions such as whether it's really okay to turn small boys into pigs because they've been bratty to their teacher).
Actually, the book doesn't explicitly say that they got turned into pigs; it says that the boys were never seen again, but a bunch of pigs turned up; which could mean anything or nothing.
The Telmarines attempt to retreat back over the river, so Aslan calls up the River-God.
And Aslan's roar that summons him. It's so powerful that it stops the Telmarines in their tracks, and the shot from above in the film emphasizes it as you see the water under the bridge ripple outward.
The White Witch tempts Caspian and then Peter with the promise of power, but Edmund gets a Moment of Awesome when he stabs her from behind and breaks her spell. Just the whole look on his face, coupled with how he succumbed to her temptations in the first movie, makes it incredibly obvious that he's learned something from the experience.
Edmund: (to Peter) I know. You had it sorted.
These are some other CMOAs Edmund got in the Film of the Book:
Thoroughly smacking down a guard during the assault on the castle with a flashlight.
Falling backwards off the tower to be picked up by a griffin.
And a minor one when he says this to Miraz: "So you're bravely refusing to fight a man half your age?" His smug smile right afterwards when Miraz has no choice but to take the bait (and visibly loses his cool while he's at it) just cements the deal all the more.
The moment right before then. Bonus points for the completely nonchalant delivery.
Miraz: Tell me, Prince Edmund...
Miraz: I beg your pardon?
Edmund: It's King Edmund. Just King. Peter's the High King. I know, it's confusing.
Also doubles as both a Badass Boast and a Stealth Insult. Edmund is referring to his throne name of King Edmund the Just. He's mocking Miraz's lack of knowledge of who he's dealing with, referencing the fact that Aslan (a figure Telemerines fear and despise, if they don't dimiss him as outright fantasy) proclaimed him (Edmund) King over Narnia rubbing Miraz's face in the fact that the Narnians aren't as dead as he would like and they consider him a usurper, AND corrects and rebukes Miraz in front of his own advisors while establishing himself as Miraz's equal, effectively proclaiming Peter higher ranked than Miraz. Less than 15 words and he manages all this. Ladies and Gentlemen, I give you Edmund the Just, King of Narnia.
In the final battle, he steals a crossbow from a Telmarine soldier and uses it to great effect; when Peter gives him a dirty look, he gives him one of his own that basically amounts to "Deal with it."
His first fight with Trumpkin the dwarf.
Trumpkin:(as Peter draws his sword) Ohhh, you don't want to be doing that, lad.
Peter:(as he hands the sword to Trumpkin) Not me. Him. (indicating Edmund)
The whole fight itself is a big CMOA for Edmund. At first, he doesn't take it too seriously, seeing as he's fighting someone half his height. But when Trumpkin starts to give it his all, you can just see the moment Edmund's eyes snap into focus, and he starts giving the duel his full attention. Seconds later, Trumpkin's flat on his ass, and Edmund's expression is a fierce, determined one you just know was one of the last few things Narnia's old enemies saw.
Him siding with Lucy about changing their plans and going down the gorge where she saw Aslan, because even though he can't see anything, he owes her one from the first book. And later, Lucy pointing out that they're going to have to go down the gorge after all — without, as Peter points out, saying "I told you so."
Edmund: The last time I didn't believe Lucy, I ended up looking pretty stupid. (gives her a soft smile)
The scene where he battles the werewolf and kills it. He's also the only one who manages to set things right when the White Witch tries to lure Caspian and Peter. He drives his sword through the ice and destroys her, finishing with a true CMOA line towards Peter: "I know...you had it sorted."
Don't forget the moment where he resets Peter's dislocated shoulder.
And the fact that he fights with TWO swords during the final battle. Kudos to Skandar Keynes for learning to wield those!
Skandar Keynes actually deserves a mention here as well, since his character got pushed to the background in order to focus almost exclusively on Peter, Susan, and Caspian; most of his lines from the book were given to other characters, he has a total of one scene with continuous dialog, and his already minor screen-time suffered even more during the editing process. Despite all of this, he still manages to shine in the few moments that he does get, and he's one of the two Pevensie children that did not end up coming across as a jerk for much of the film.
Miraz is completely evil, but he's also downright formidable. He's wearing nothing more than a night-shirt, while his justifiably enraged nephew has him at sword-point, but his first response is to nonchalantly snark about it, then deliver a "Reason You Suck" Speech designed to get right under Caspian's skin, bullying him backwards while still at sword-point and with blood drawn from his neck, and to get his wife - who is understandably horrified when she finds out that her brother-in-law, Caspian's father, was murdered by Miraz (he was meant to have died in his sleep. Per Miraz, this was true... more or less) - to cast aside her uncertainty and fire her crossbow by invoking her Mama Bear instincts. If it wasn't for his Bad Boss tendencies causing both Lords Glozelle and Sopespian to go along with Edmund manipulating him into a duel with Peter, and the intervention of Aslan, he'd most probably have won.
Susan gets one too, when she manages to take out almost all of a bunch of riders pursuing her and Lucy through the woods. Okay, Caspian has to dispatch the last one, but still...
Don't forget during the castle fight, she shoots a guard with an arrow, then stabs one with another arrow and follows that by throwing the same one into the chest of another guard.
Pattertwig:(enthusiastically) We can collect nuts!
Reepicheep: Yes, and we'll throw them at the Telmarines! (sarcasm washed away) Shut up.
At one point, he binds and gags a (non-talking) cat - too quickly and subtly for the cat to do anything, even make a fuss.
Asterius, the Minotaur who holds up the castle gate, even after being peppered with arrows, so that the Narnian army can retreat, also deserves a mention.
Yes, yes he does. As does the centaur that's stuck on the wrong side of the gate in that scene who sees his father, nods at him, then turns around and rides into the guards. They will kill him, but by Aslan, he'll take them down with him.
Caspian gets knocked to the ground by Lord Glozelle, but he hesitates long enough for the Trees to come alive once again and he gets whacked about by their roots.
Afterwards, Peter helps Caspian up, and it's a testament to Peter's faith in his sister that he immediately says that this is Lucy's handiwork. She's found the Great Lion, and Narnia is coming alive again, all because of her.
The fact that Lord Glozelle hesitates at all. Throughout the film, he's portrayed as being something of a reluctant follower, and he's finally given a chance to cement himself on the side of good when he hesitates to kill Caspian, even though the boy was completely defenseless in the moment.
Aslan waking up Narnia with one, majestic roar.
Lucy gets a Crowning Moment of Awesome near the end. The enemy army is retreating across a bridge from the Narnian army, when Lucy appears at the far end. The minute she draws her dagger, the army stops in its tracks. Then again, there's a lion (which is God) standing right beside her.
To be fair, they stop before they even see Aslan. It's almost like they did the math and knew exactly who she was. Aslan was just the confirmation that they were indeed screwed.
The film's version of the river-god gets an extra one beyond what his book counterpart did, for freeing himself from his "chains".
