The promotion for ABC's Once Upon a Time continues to center around the inclusion of the massively popular Disney film Frozen, with the latest poster mirroring previous OUAT posters except with a Frozen twist.

Once Upon a Time Season 4 Trailer Shows 'Frozen's Elsa Proclaiming, 'I'm The Queen,' Regina Not Amused

The Once Upon a Time Facebook account released the new poster for Season 4 of the series, featuring an extreme closeup of Queen Elsa (Georgina Haig) and her big blue eyes. A frozen blue apple covers her mouth, mimicking the poster used for Season 3 which has Regina (Lana Parrilla) with a giant red apple covering her mouth.

The new Frozen-inspired poster has icicles dripping down in front of Elsa along with the slogan "Storybrooke has frozen over."

Elsa Creates 'Powerful Snow Monster' To Fight Against Storybrooke Residents

As previously reported, the Season 4 premiere is titled A Tale of Two Sisters, which is a clear nod to Frozen sisters Elsa and Anna (Elizabeth Lail).

In the episode, "a scared and confused Elsa finds herself in Storybrooke and, fearful of the intentions of its residents, creates a powerful snow monster for protection," according to a press release for the episode. "Meanwhile, in Arendelle of the past, as Elsa's sister Anna's wedding to Kristoff [Scott Michael Foster] nears, Anna discovers that their parents - who died on-ship during a violent storm - were heading to a mysterious destination in a quest that may have held the secret to containing Elsa's out of control Ice powers. And against Elsa's wishes, Anna wants to finish their journey to find out what they were looking for."

The new season will be focusing on the Frozen for the first half, though it is not known if they will continue into the second half.

Once Upon a Time Season 4 is set to debut Sunday, Sept. 29 at 8 p.m. ET/PT on ABC.
