Wicked is a musical that tells the story of the witches in
The Wizard of Oz before Dorothy shows up. There are a few similarities in characters in Wicked and Macbeth that I noticed.
**Wicked spoilers**
Lady Macbeth is like Elphaba. Elphaba is very smart and starts out just trying to make her family proud; however, she ends up getting in trouble with the law and turns against the government because she thinks they are doing the wrong thing. She also tries to help her sister save Boq when a spell goes wrong, but ends up turning him into the Tin Man. She has a great line "let all Oz be agreed, I'm wicked through and through" and she later becomes the Wicked Witch of the West, and at the end of the show pretends to die when Dorothy dumps water on her. Likewise, Lady Macbeth is clever and bold, and tries to be faithful to Macbeth by helping him become king. Then she ends up going too far and, after the pair has murdered two men and a family, she feels the regret (and obviously, like Elphaba, what she did was treasonous). However, she actually does end up dying at the end, having become so corrupted that she is haunted every moment.
Macbeth is like Nessarose (Elphaba's sister). Nessa starts out as simply a frail girl attending school, often given more privileges than her sister. However, her sister enchants her shoes to make her able to walk (she was in a wheelchair) and she works with magic. She gets carried away thinking that she can perform any spell correctly, and ends up almost killing her love interest Boq. Similarly, Macbeth at first helps his country fight against the Norwegians, but later he works with Lady Macbeth against the king, and then he turns against anyone who would obstruct him from keeping the throne, without hesitation.
