'Once Upon A Time' Season 4 Teaser Released; Storybrooke Greeted With An Icy Entrance By Queen Elsa [VIDEO]

The newest "Once Upon A Time" season 4 teaser has been released and it appears that Storybrooke is about to get its icy dose of Frozen's Queen Elsa.

The "Once Upon A Time" season 4 teaser shows the much awaited and talked about plot lines the show has ever come up with to date: the coming of Queen Elsa of Arendelle, whose character will be played by "Fringe's" Georgina Haig.

In a Hollywood Reporter exclusive, the "Once Upon A Time" season 4 teaser shows Queen Elsa leaving her icy trail in the town's popular spots.

While Elsa's face was not revealed in the teaser, it was rather obvious that her arrival poses a threat to Storybrooke's resident antagonist Regina a.k.a. Evil Queen, played by Lana Parilla, with Regina's voice saying "Here we go again..." on the video.

Queen Elsa's surprise appearance casts a rather unnerving edge to the town, leaving its citizens - Mary Margaret a.k.a. Snow played by Ginnifer Goodwin, David a.k.a. Charming played by Josh Dallas, Mr. Gold a.k.a. Rumpelstiltskin played by Robert Carlyle and Captain Hook played by Colin O'Donghue - frazzled.

Frozen fans will be more than happy to know that "Once" will feature more characters from the film including favorites Anna to be played by Elizabeth Lail; Kristoff to be portrayed by Scott Michael Foster; Prince Hans, who will be given life to by Tyler Jacob Moore, and Pabbie the Troll King, which will be played by Jon Rhys-Davis.

According to Bustle, Elizabeth Mitchell will also be part of the show's latest season and will take on a Frozen character as well, but details have yet to be released.

A special peek at the newest season of "Once," which featured Elsa and Anna, was shown in this year's Comic-Con.

"Once Upon A Time" season 4 will begin on September 28 on ABC.
