As "Once Upon a Time" season 4 begins filming, spoilers regarding some of its characters have surfaced.

Since the "Once Upon a Time" season 3 finale, it's been all about Rumplestiltskin and that pesky dagger of his, but spoilers have also surfaced about the now married Belle.

According to TVLine, fans will see Belle's life before she met Rumplestiltskin, and it seems we will see the character as a waitress of sorts.

Joining Belle will be Hans from Disney's "Frozen," alongside Anna, Elsa, and Kristoff for "Once Upon a Time" season 4. Georgina Haig has already begun filming as Elsa, while Elizabeth Lail will play Anna, and Scott Michael Foster will portray Kristoff. Spoilers also confirm that Elizabeth Mitchell will join the cast as either the original Snow Queen, or Anna and Elsa's supposedly-dead mother.

Meanwhile, "Once Upon a Time" is also spurring fans to talk about the next fairytales characters they'd like to see appear on the series after the "Frozen" arc.

"It'll be nice to have Aladdin and Jasmine for 'Once Upon a Time," commented Jas on E! Online. "Too bad they already used Jafar for 'Wonderland.'"

"I still feel they need to redo Rapunzel and bring Jazmin, Aladdin, and Jafar," wrote Victor F. "'The Jungle Book' is a really good idea, same as 'Brave' and The Frog Prince. But there are other fairytales that need the 'Once Upon a Time' treatment like Briar Rose. I am so for the idea to bring Cruella, I would love to see that matchup between her and Regina.
