context: Eva Bella and Spencer Ganus were cast to portray Elsa as a young child and as a teenager, respectively. Actress and singer Megan Mullally was originally cast to voice an adult Elsa. but was replaced by Idina Menzel, a Broadway actress and singer best known for performing as Elphaba in "Wicked". Menzel already knew Kristen Bell, who voiced Anna, and had previously auditioned for a lead role in the 2010 Disney film "Tangled". She was not cast for the part, but the casting director recorded her singing and later showed the recording to "Frozen"s film executives. Menzel was surprised when she was subsequently asked to audition, and she received the role after reading the script out loud. In interviews, she acknowledged similarities between Elsa, her then-current role, and Elphaba, her previous role. Namely, she said, they were both very powerful and very misunderstood individuals. She further said that she related to the characters, having hidden her singing talent from her peers at school. "I didn't want to alienate anyone," she explained. "If everyone was singing along in the car to a Madonna song, I didn't join in because when we're younger we're afraid of sticking out or showing off, when in fact we should own those things that make us really unique."
