once upon a time season 4 trailerThe fourth season of "Once Upon a Time" is almost upon us, and with it comes a new, extended look at what's in store for viewers and the residents of Storybrooke.

The biggest change is that characters from "Frozen" have entered the "Once" world, and as we see in this promo, they aren't exactly making friends with the locals. Elsa (Georgina Haig) immediately declares herself queen, which irks Regina (Lana Parrilla), and sets in motion a battle royale between the two powerful, power-hungry women.

Viewers also get a sneak peek at some familiar faces, too, including Belle and Rumplestiltskin, who dress like their animated Disney counterparts (Beauty and the Beast, respectively) and take a whirl on the dance floor. It's all positively enchanting, though with Elsa and Regina gearing up for all-out war, things probably won't remain that idyllic forever.

"Once Upon a Time" is set for its fourth season premiere on September 28 on ABC.
