Torvald has treated Nora like a toy through out their marriage. He was enraged at his wife over Krogstad's letter exposing the truth about Nora, but when he got an apology letter from the same person, he took back everything he said and pretended that nothing happened. Just like Nora's dad, Torvald loves Nora as a possession, not really as a person. This results in Nora feeling like an object that has been passed down to a stranger after her dad's death. Out of all of the characters that are more significant, Nora would have to be that significant character. I see her grow as a character during the last act and realize that she needs to reevaluate her life in the end. The ending is bitter sweet because on one hand, she tries to find herself after eight years of meaningless marriage, but on the other hand, she left her husband and three children during the night of Christmas eve. I would not change the ending because it had a satisfying resolution to Nora, even if it raises questions about the aftermath for Torvald and her children. If I were to make a staged production of A Doll's House, the actress for Nora would have to be Sara Bareilles. She's got the looks and the energy like Nora and she's got the voice that fits her well. I feel like Hugh Jackman would fit perfectly for the roll as Torvald because he has this rough voice that feels like a manipulative husband. The fact the Hugh had also done a Broadway show is an added bonus. These rolls are very important because the character has to be represented properly and feel like that they are real.
