In May, the Season 3 finale of "Once Upon a Time" revealed that Elsa from Frozen is going to appear on the fourth season with the below tease. Now, ABC has confirmed that the animated hit's Anna and Kristoff will also appear.
The network has confirmed via TVLine that newcomer Elizabeth Lail will play Anna, Queen Elsa of Arendelle’s younger sister, while "Greek" grad Scott Michael Foster has landed the recurring role of Kristoff.
According to the site, Anna in "Once Upon a time" is described as a "fun-loving, fearless optimist who often gets herself into situations where she is in over her head, yet is able to triumph due to her resourcefulness and can-do spirit. She values her relationship with her sister Elsa above all else."
Kristoff, meanwhile, "is a hearty, salt-of-the-earth ice cutter whose sometimes-gruff demeanor can hide his deep love for Anna and her sister Elsa. When we first meet him on Once, he is adjusting to life at the castle — including sleeping indoors for the first time in his life."
