'Frozen 2' spoilers, plot news: Director gives clues about Anna and Elsa's brother

Well-loved sisters from all-time favorite "Frozen" will grace the movie screens once more, as it was recently confirmed that "Frozen 2" is in the works. Given the first film's success, fans are in high hopes that the upcoming sequel to "Frozen" will live up to its predecessor.

MTV interviewed "Frozen" director Chris Buck with regards to the much-anticipated part two of the movie, and he gave a few hints about the how the story will play out. Along with co-director Jennifer Lee, he discussed how the movie is now in its early stages of development.

"We're just starting. Jen [Lee] and I are just getting back into the story room together and throwing ideas around. We have an overall idea, a concept, which I think is a very strong one. I'm very excited about doing it," he mentioned.

As for the values that the story will impart on its viewers, "We have two very strong female leads in 'Frozen'...We will keep that going in the next one. We will tackle other issues that, I think, are out there today that boys and girls, men and women, are dealing with," Buck added. Moreover, the filmmaker stressed the importance of including life lessons in the movie, especially since it is more targeted to the youth.

While the script remains in the works, fan get more creative as they try to sort out where the movie's story will go. One of them involves a Tarzan reference to the story, making him Anna and Elsa's brother.

"I said, 'Of course Anna and Elsa's parents didn't die," said Buck. "They get shipwrecked, and somehow they really washed away far away from the Scandinavian waters, and they end up in the jungle. They end up building a tree house and a leopard kills them, so their baby boy is raised by gorillas. So in my little head, Anna and Elsa's brother is Tarzan," he concluded.
Buck seemed open to the possibility of bringing in Tarzan to 'Frozen 2,' but as for now, he leaves it up to the audience to believe in anything they want. "I say, whatever people want to believe, go for it. If you want to tie them all together, then do it. That's the spirit of Disney," he explained.
