The film's producer Peter Del Vecho recently admitted the plot completely changed from the start.
“When we started off, Anna and Elsa were not sisters. They weren’t even royal,” he said in an interview with Entertainment Weekly.
“Instead, Elsa was a full-blown villain because she had been stood up at the altar on her wedding day, and chose to freeze her own heart - leading viewers to believe she’s the one in the prophecy destined to ruin Arendelle.
“We started out with an evil female villain and an innocent female heroine and the ending involved a big epic battle with snow monsters that Elsa had created as her army.”
He said in that version, Prince Hans planned to create an avalanche to destroy their town but Anna convinced to Elsa swoop in and save everyone – causing her heart to unfreeze.
Peter said the ending felt too predictable.
“The problem was that we felt like we had seen it before,” he said.
“It wasn’t satisfying. We had no emotional connection to Elsa - we didn’t care about her because she had spent the whole movie being the villain. We weren’t drawn in. The characters weren’t relatable.”
The movie then became about love vs fear over love vs evil and so Frozen as we know (and love) was born.
We’re so glad we got this happy ending.
