This summer, Elizabeth Mitchell was cast for the Season 4 Frozen storyline of Once Upon a Time, but her role was shrouded in secrecy.
The Daily Mail has revealed pictures of Mitchell in Snow Queen attire.
While Elsa is causing trouble in Storybrooke, as seen in last week's premiere, she's not the Big Bad of the season and OUAT has a habit of casting roles of Lost alumni, like Alan Dale as King George, and Naveen Andrews as Jafar, in Once Upon a Time in Wonderland, as villains.
Edward Kitsis and Adam Horowitz, OUAT show runners, revealed to Entertainment Weekly last week that this role would show a villainous side of Elizabeth Mitchell. Horowitz told EW:
"[Elizabeth's] not just working with the Others because she has no choice, but a truly villainous side. We can't wait to scare everyone."
It is not known when or how Mitchell will first appear in Storybrooke.
Once Upon a Time airs Sundays on ABC.
