Oscar's arrival in Oz. the black and white fading to color and the 1.33:1 Academy ratio slowly expanding to full 2.35:1 widescreen are perfectly in sync, and the color never goes any less brilliant from that point on.
Oz's Batman Gambit at the movie's climax isn't exactly original, but that makes it no less incredible. Point in case: he first develops a plan that ends up with the entire winged baboon army completely incapacitated, and then, using smoke and mirrors and fireworks, convinces two very definitely real and incredibly powerful witches that he is an immortal being able to easily overpower both of them. It's as awesome as it sounds.
His performance is so awe-inspiring that Evanora and Theodora become convinced that he's the real deal and that they're no match for him, so they decide to flee.
Giving Theodora an interesting moment herself. Evanora bolts the moment things get a bit hairy...Theodora stands her ground until Glinda escapes and she has to duck a few fireworks lobbed at her head.
Likewise Evanora sends her guards to kill "The Great and Powerful Wizard of Oz" and visibly freaks out when they fail. Theodora shouts her defiance as she launches a fireball at him.
Theodora's entrance as the Wicked Witch. Evil Is Cool indeed.
Glinda's final battle against Evanora. Considering that her magic was not really used offensively over most of the movie, it's amazing how she overpowers Evanora and shatters her magic pendant, finally showing herself to be the powerful witch she really is.
The scriptwriters deserve a MoA of their own, for deftly Writing Around Trademarks while still loading the film with so many brilliant references to the classic Oz film.
