Fan Casting Elsa in Frozen (Live Action)

Elsa is the firstborn daughter of King Agnarr and Queen Iduna, the older sister of Anna and the former queen of Arendelle. She was born with the powers to manipulate ice and snow and, as a child, used them to entertain her sister. However, after Elsa accidentally hurt Anna with her powers and Anna's memories had to be erased, she grew afraid of her powers and was unable to appropriately control them. She lived in fear of hurting anyone with her powers, and spent much of her formative years shut out from the world. Although it pained her greatly to do so, Elsa also found it necessary to distance herself from her family so there would be no risk of causing further harm.
