"Frozen" wasn't supposed to have such a warm ending.
The animated phenomenon was originally going to have an ending that was much more closely aligned with the Hans Christian Andersen tale on which it's based.
"Frozen" producer Peter Del Vecho revealed to Entertainment Weekly the original version of the film wasn't a heartwarming tale of sisterly love.
Del Vecho says princess sisters Anna and Elsa weren't related in early scripts. He says "Elsa was a self-proclaimed Snow Queen, but she was a villain and pure evil."
The drafts included a finale with Elsa using her powers to save the kingdom, but Del Vecho says the character's evilness gave them "no emotional connection" to her. The filmmakers finally got things right after reworking the script.
A sequel to the film is currently in production.
