Once Upon A Time New Stills, BTS and Details of “A Tale of Two Sisters”

With a couple of weeks away from the season 4 premiere of Once Upon A Time we are slowly getting stills of the first episode “A Tale of Two Sisters” that introduces the Frozen characters. Below you can find behind-the-scenes images and stills of Elsa, Anna, Kristoff and Sven. Along with the show favorites Hook, Emma, Regina and returning character Sidney Glass/Magic Mirror.

Also, we are finding tidbits of story lines that are piecing together what the Frozen characters are up to in Storybrook. In the season 4 opener we are set in Arendalle:

“where in a flashback we’ll get to see Elsa (Georgina Haig) boss her future brother-in-law around, as Kristoff (Scott Michael Foster) will need to learn to leave Sven in the stables and start sleeping in the castle. Elsa is thrilled her sister Anna (Elizabeth Lail) is getting married, though she wishes her adventurous sister wouldn’t complete the quest in finding the secret behind her icy-powers, the one their parents had started before they got killed.

Watch out for Once Upon A Time season 4 September 28th at 8/7c on ABC.
