That's according to the animated film's producer Peter Del Vecho, who says they completely re-wrote the ending.

"When we started off, Anna and Elsa were not sisters," he told EW.

"They weren't even royal. So Anna was not a princess. Elsa was a self-proclaimed Snow Queen, but she was a villain and pure evil - much more like the Hans Christian Andersen tale."

Based on a popular picture book, the basic idea could hardly be more universal: life is going along just swimmingly for 7 ½-year-old Tim (voiced by Miles Bakshi), until his parents (Lisa Kudrow, Jimmy Kimmel) inform him that he's about to have a baby brother.

Because a grown-up Tim (Tobey Maguire) narrates the story, a bit of hyperbole is reasonable, like his recollection of the baby (Alec Baldwin, in an inspired casting stroke) motoring up to the driveway in a cab, already wearing a little suit and tie.
