Disney remains mum about the plot of “Frozen 2” but speculations suggest Anna could be the villain in the upcoming sequel.

Movie Pilot said “Anna may end up breaking away from her friends and going on her own” because of the effect of the frozen heart which was seen in the first movie.

The site also took a look into the classic fairytale “The Snow Queen” which was played by Idina Menzel as Elsa in the film adaptation.

In the story, the Ice Queen and the troll are villains, said Movie Pilot. But in the Disney movie, they were the kind characters.

The concept of the frozen heart was present in the blockbuster 2013 movie but it did not deal so much on its effect, Movie Pilot explained. In the movie, viewers watched Anna recovered from the frozen heart after it was melted by her sister Elsa.

Movie Pilot said the idea of hatred as after effect of the frozen heart could be a possible plot in “Frozen 2.”

Disney had confirmed that the Anna, Elsa, Kristoff, and Olaf will return in the big screen and it has been reported that “Frozen 2” will be released in 2018. “Frozen” stars Menzel (Elsa), Kristen Bell (Anna), Jonathan Groff (Kristoff), and Josh Grad (Olaf) will also reprise their respective characters.

Disney Chief Creative Officer John Lasseter said in an official statement, “We enjoyed making “Frozen Fever” so much and being back in that world with those characters. Jennifer Lee and Chris Buck have come up with a great idea for a sequel and you will be hearing a lot more about it and we’re taking you back to Arendelle. We are so excited about that,” Screen Cast wrote.

“Frozen” earned $400 million in the U.S. and over $1.2 billion worldwide, according to Screen Crush. These do not include the “Let It Go” soundtrack that became an international hit too.
