The ABC fantasy series has cast Georgina Haig as Frozen's well-meaning ice queen. The 28-year-old Fringe actress joins newcomer Elizabeth Lail as Princess Anna and Greek actor Scott Michael Foster as Kristoff.
TVLine reports that Once Upon a Time's Elsa still struggles to control her icy powers. Her love for her sister Anna keeps her magic in check, but she is keenly aware of the damage another loss of control could cause.
"The thing we love about Elsa is she is perceived to be a villain but is clearly misunderstood," show co-creator Eddy Kitsis shared previously. "That goes to the heart of our show."
Elsa, Anna and Kristoff make their debut this fall on the fourth season of Once Upon a Time.
