As stated before, Ahamo is Omaha in reverse. William Jennings Bryan: Nebraskan, perennial Presidential candidate and "hot air balloon" in his own right, was no doubt the target of this reference in L. Frank Baum's story.
Goof: When DG pulls Azkadellia from the energy-platform, the evil witch is sucked out of Azkadellia's body. In this scene you can clearly see that the little "flying monster"-tatoos are left on Azkadellia's decollete. In the next camera-angle the monsters are gone even though they have not been sucked out and the evil witch has not been defeated yet (which would have destroyed the monsters anyway, I think).
Goof: When Glitch is telling Cain the number to shut off the machine, they get all the way to the last one, but the enemies break in before Glitch has time to say it. The henchman types back the numbers to get the machine to full power. Then, Cain, Glitch and Raw knock them out and Cain resumes where he left off. He only asks for the final number, but wouldn't he have to do all the other numbers again?
When DG discovers her mother's hidden message, Azkadellia finds it also. Though, the mother's message is different for Azkadellia than it was for DG.
In the book The Wonderful Wizard of Oz, the Wizard of Oz isn't a wizard at all, but a con man, trickster, etc. He is from Omaha, and he was flying in a hot air balloon when he got trapped in a storm and landed in Oz... much like Ahamo. And as mentioned previously, Ahamo is backwards for Omaha.
Error: When Glitch is telling Cain the numbers to submit to stop the machine, he tells them they are the numbers that start them only in reverse order. The numbers in order he gives are 1066, 1418, 1666, and 1789. Cain enters the numbers and the machine starts to shut off. The enemy comes in to stop them and turn the machine back on. They force Glitch to tell the numbers again in reverse. He tells them 1789, 1666, 1418, and 1385. The machine starts back up although the last number was wrong. It should have been 1066 and not 1385.
We learn that at least one of the forms of currency in the O.Z. is in platinums.
Ahamo's name spelled backwards is Omaha, a city in Nebraska.
Ahamo: Like it or not, DG, I'm your father.
DG: No, no. I had a real father. He was a robot, but he was there for me. He was a good guy.
Cain: It amazes me that you once influenced the Queen...
Glitch: I know! Me too.
Cain: I know what you're doing, kid... I've led men through battle myself.
DG: And, um... How am I doing?
Cain: Well, there's less hugging when I do it. But not so bad.
DG: I hope this is the perfect day.
DG: Two little princesses dancing in a row
Spinning fast and freely on their little toes
Where the light will take you
No one ever knows
Two little princesses dancing in a row
DG: (as the sun rises over the O.Z.) That's the O.Z. I remember. I'm so glad to be home.
Cain: If you don't have heart... you have nothing.
DG: (to Azkadellia holding the emerald) Green's not your color.
Cain: Trust me the realm of the unwanted is here... somewhere. (Camera zooms out to a large empty field)
Cain: (looking at the iron suit) What's that doing here?
Jeb: I keep it to remind me, to remind everyone what we are fighting for.
Zero: You surprise me, Cain. Not a lot of men make it out of the iron suit with their sense of humor intact. Let's see how funny you are when you're... hanging from the gallows in Central City square.
Glitch (looking at the fortune teller with six arms): Can't say it didn't welcome us with open arms...
Cain: (to Toto) I'd shoot you in the heart if I thought you had one.
(While playing on the lake)
Young Azkadellia: Flat rocks fly...
Young DG: Round rocks die.
Original International Air Dates:
Slovakia: January 5, 2011 on Markiza
The gray gale turns out to be Dorothy waiting to hand over the emerald at the old farm in Kansas. In the 1939 movie, Kansas was filmed in black and white, hence the name, "Gray Gale."
DG: What are those?
Cain: Breadcrumbs for Azkadellia.
This is a reference to the fairy tale "Hansel and Gretel", in which the two children leave breadcrumbs to find their way home. Tutor had been leaving little devices behind as the group traveled so that Azkadellia would know which way they were heading.
Both the witch in Tin Man and the Wicked Witch in The Wonderful Wizard of Oz melted upon death.
The Dorothy Gale that DG meets and the silver slippers are all in the original book The Wonderful Wizard of Oz.
The hot air balloon that DG and her father use is taken from The Wonderful Wizard of Oz. It is what Dorothy and the Wizard travel in to return home.
