"Wicked" is a popular musical that tells the backstory of the iconic characters from "The Wizard of Oz," particularly focusing on the witches Glinda and Elphaba.  

While there's no specific movie adaptation that focuses on "12 stories," it's possible that you're referring to a potential film adaptation or a particular aspect of the musical. 

Initially portrayed as popular and superficial but later shows depth and compassion. 

Initially misunderstood due to her green skin, she is intelligent and passionate about social justice. 

A prince who becomes romantically involved with both Glinda and Elphaba. 

Madame Morrible, Dr. Dillamond (an animal professor), Nessarose (Elphaba's sister), and Boq (a Munchkin who pines for Glinda). 

The story explores how Glinda and Elphaba first meet at Shiz University and their complicated relationship. 

Elphaba discovers her magical abilities and becomes an outcast due to her green skin and unconventional beliefs. 

Political intrigue unfolds as the Wizard manipulates public perception of Elphaba, leading to tragic consequences. 

Themes of friendship, love, betrayal, and the nature of good and evil are central to the story. 

As of my last update in January 2022, a film adaptation of "Wicked" had been in development for many years.
