Despite Disney's claim that the hit animation "Frozen" is based off of Hans Christian Andersen's "The Snow Queen," a Peruvian author is claiming otherwise in a recent lawsuit.

The animation film has grossed more than $1.2 billion globally nearly a year after its release, and is the highest grossing animated film of all time.

Some suspect Isabella Tanikumi (birth name Amy Gonzalez), wants in on that profit, Peru This Week reported.

She claims Disney plagiarized her 2010 autobiography, "Yearnings of the Heart," and details how the movie has a likeness to her book.

Tanikumi, born and raised in Huaraz, Peru, filed a $250 million lawsuit against Disney recently.

Her book details her life in Peru, the death of her sister, and "a dialogue with her long lost love, Eduardo," according to Philly.com.

"Frozen," on the other hand, follows sister Anna as she treks through blizzard conditions to bring sister Elsa back to their icy kingdom. There is no long lost love story.

But Tanikumi insists that the similarities in the plots include two sisters who have tragedies, romances, conflicts, isolation and loneliness, according to Peru This Week.

And the snow-covered mountains, which Disney said were inspired by those in Norway, where a crew was specifically flown to gain inspiration, are actually from Huaraz, Tanikumi said.

Another similarity, she said, has been that two of her past lovers were named Hans and Christoff, and the two lead male roles in the movie are Hans and Kristoff.

Regarding the award-winning song "Let it Go" from the movie's soundtrack, Tanikumi said that songwriters have used her books for material before.

Tanikumi resides in northern New Jersey, but little else is known about the author, according to NJ.com.

Disney has not released any statement or comment regarding the lawsuit.
