Goofs

When Elphaba and Glinda enter the Emerald City, Glinda hands the guards her coat as she exists the train. She is not wearing it for much of 'One Short Day'. However, when she and Elphaba enter the Wizard's palace she is once again wearing her coat.

Elphaba's bag containing the Grimmerie is not on her when she leaves Emerald City on her broom.

When the students of Shizz are seeing off Elphaba Nessa sees the way Boq looks at Glinda after she announces her name change and turns to leave and then the camera cuts to Glinda and then cuts back to Nessa turning again to leave.

During 'What Is This Feeling?', while the screen is split, Elphaba looks to her left and uses her right arm to grab her covers in order to throw them off. But in the next shot she's facing her right and using her left arm to throw off the covers which is the correct direction for the room.

During "Dear Old Shiz", shortly before Galinda starts singing, there is a close up of the back of Elpheba's head. As can be seen in the background of that shot, everyone makes way for her, leaving only Galinda who didn't notice Elpheba yet. Yet, when Galinda sings and the camera switches to a perspective in front of her, there are still people behind her and they only move simultaneously with Galinda recoiling.

In the movie the two letter abbreviation for Nebraska, NE is used. Two letter state abbreviations weren't introduced until 1963, long after the Wizard left for Oz. The correct abbreviation for the time would likely have been Nebr.

In the opening scene where the monkeys are flying near the waterfalls, the order of colors in the rainbow are opposite of actual rainbows. In normal (primary) rainbows, red is on the outside of the arc and violet is on the inside. In this scene, the colors are reversed where red is on the inside of the arc and violet is on the outside.

It's possible that the magical land of Oz doesn't obey the same laws of nature, but most likely this is an error made during filmmaking.

The painted rainbow on stage during Wizomania, however, is correct, implying that rainbows look the same there.

In the beginning, as Scarecrow, Dorothy, Tin Man, Lion, & Toto walk from Elphaba's castle towards the Emerald City (after having "killed" the witch), Dorothy carries the Witch's broom with all its bristles. But in The Wizard of Oz (1939), the Witch burns the bristles of her broom to burn Scarecrow, and when they present the broom to the Wizard, the bristles are burned off.

As evidenced by Nessarose being given Silver Shoes, rather than Ruby Slippers, the film isn't a prequel to the 1939 film, but rather its own continuity. It's more than likely that the state of Elphaba's broom will be consistent with the upcoming Part Two.

When Glinda and the Munchkins sing No One Mourns the Wicked, there was no evidence of the Kansas farmhouse that had recently fallen from the sky and crushed Nessarose. However, "No One Mourns the Wicked" is a song celebrating the death of Elphaba, the wicked witch of the west, not her sister's. Her sister's death happened quite a while before that, enough time that the munchkins probably had her and the house that crushed her removed from the village, since Dorothy's entire adventure takes place between Nessa's death and Elphaba's.

Elphaba loses control of her powers whenever she gets angry. Yet, when Galinda teases her with her mother's bottle and she yells at her, nothing happens. Though, given that Elphaba is not in her strongest emotion at this point, not to mention having no such build-up pressure to it either, her magic doesn't respond as a result.

In the classroom scene where Elphaba causes the flowers to rise in the air and the pollen sends the students to sleep, you can clearly see a wire suspending one of the flowers as it moves. It will be interesting if this gets corrected for the streaming and DVD release of the film.

When the balloon arrives with Elphaba's invitation to visit the Wizard, a blur can be seen moving across the steps in the background. This is caused by the post-production removal of the wire supporting the balloon.

Right after "Dear Old Shiz" the scene where Galinda tells Elphaba the iconic line "You're green!" in one of the parts where it is a close up of Cynthia Erivo (Elphaba) you can clearly see she has a wig on.
