We reported last week that a clip was shown to the Comic-Con crowd where Anna and Elsa were visiting their mother's gravestone, with Elsa revealing she had a "surprise" in store for Anna and Kristoff's upcoming wedding.

Aside from Georgina Haig, Scott Michael Foster and Elizabeth Lail, other Frozen roles include Elizabeth Mitchell as a mysterious character who has ties to both Storybrooke and Arendelle, Tyler Jacob Moore as Hans and John Rhys-Davies as the rock troll Pabbie.
