Plot
On reaching the Emerald City, Oscar meets
Evanora (
Rachel Weisz), Theodora's sister, who is skeptical of Oscar being the foretold wizard. Evanora tells Oscar that the Wicked Witch resides in the Dark Forest and can be killed by destroying her
wand, the source of her power. Oscar and Finley are joined en route to the forest by China Girl (
Joey King), a young, living
china doll whose home and family were destroyed by the Wicked Witch. The trio reaches the forest and discovers the "Wicked Witch" to be
Glinda the Good Witch (
Michelle Williams), who tells them Evanora is the true Wicked Witch. Evanora sees this with her
crystal ball and manipulates Theodora against Oscar by showing him together with Glinda, saying he is trying to
court all three witches. She offers the heartbroken Theodora a magic apple she promises will remove her heartache, which Theodora eats, transforming her into a heartless, green-skinned Wicked Witch.
Glinda brings Oscar's group to her domain of Oz to escape Evanora's army of
Winkies and flying
baboons. She confides with Oscar that she knows he is not truly a wizard, but believes he can still help them stop Evanora, and provides him an "army" of
Quadlings,
tinkers, and
Munchkins to do it. Theodora enters Glinda's domain and angrily reveals her new, hideous appearance to Oscar before threatening to kill him and his allies with the Emerald City's well-prepared army. Oscar despairs that his army cannot defeat the Wicked Witches, but after telling China Girl about his exploits, he realizes they can fight using
prestidigitation.
Glinda and her subjects use an automated army of
scarecrows blanketed by thick fog to trick the Wicked Witches into sending their flying baboons through a
poppy field that puts the baboons to sleep. However, two baboons manage to capture Glinda, who is brought to the city square to be executed. Meanwhile, Oscar infiltrates the Emerald City with his allies, only to seemingly abandon them in a hot air balloon loaded with the king's gold, which Theodora destroys with a fireball. Oscar then secretly reveals himself to his friends, having faked his death. Oscar uses a hidden
smoke machine and
image projector to present a giant,
holographic image of his face as his "true" form, and a
fireworks display to attack and intimidate the Wicked Witches. Evanora fearfully hides in her castle while Theodora flies from the city on her broom, unable to hurt the "invincible" wizard. China Girl frees Glinda, who defeats and banishes Evanora, destroying the Wicked Witch's necklace that hides her true,
crone-like appearance before she is carried off by flying baboons.
The film concludes with Oscar, now king of Oz, using his projector to sustain the belief that he is still a powerful wizard and keep the citizens of Oz united against the Wicked Witches. He also presents gifts to his friends:
Master Tinker (
Bill Cobbs), who helped build his machines, receives a
Swiss Army knife; Knuck (
Tony Cox), the grumpy city herald and an ally of Glinda, receives a mask with a smiley face; the long-suffering Finley receives Oscar's friendship; and China Girl accepts her friends as her new family. Finally, Oscar takes Glinda behind the curtain of his projector and kisses her.
[edit]Continuity
References to characters from the previous film include: the
Scarecrow, who is built by the townspeople as a scare tactic; the
Tin Man, whose creator is introduced as the Master Tinker; and the
Cowardly Lion, who is frightened away by Oscar after attacking Finley.
[3] Theodora's tears leave burn marks on her face, foreshadowing her
weakness to water. Glinda travels in giant bubbles, hinting at her entrance in the classic film. Annie (Michelle Williams) informs Oscar that she has been
proposed to by a man whose surname is Gale, presumably hinting at
Dorothy Gale's parental lineage.
[4] Additionally, a number of actors who play Oz characters make cameos in the Kansas segments.
