Pabbie was originally voiced by Ciarán Hinds in the Disney film, and Hans was played by Broadway's Santino Fontana. OUAT's FROZEN storyline will feature Elizabeth Lail (Anna), Georgina Haig (Elsa), Scott Michael Foster (Kristoff) and Elizabeth Mitchell in a role to be announced.

Davies is probably best known for playing 'Gimli' in The Lord of the Rings trilogy. Among his other screen credits are the Indiana Jones movies, The Untouchables, Shogun, Sliders, Robin of Sherwood, The Living Daylights, I, Claudius, Freelancer and more.

A relative newcomer, Moore has appeared on TV in Shameless, NCIS, Private Practice, Rules of Engagement, GCB, Emily Owens, M.D., Revenge and more.

The upcoming season is expected to take place following the events depicted in the Disney film. A sneak peek at season four of Once Upon a Time was screened last weekend at the San Diego Comic-Con. Check it out here.

FROZEN tells the story of fearless optimist Anna (voice of Kristen Bell) who sets off on an epic journey-teaming up with rugged mountain man Kristoff (voice of Jonathan Groff) and his loyal reindeer Sven-to find her sister Elsa (voice of Idina Menzel), whose icy powers have trapped the kingdom of Arendelle in eternal winter. Encountering Everest-like conditions, mystical trolls and a hilarious snowman named Olaf (voice of Josh Gad), Anna and Kristoff battle the elements in a race to save the kingdom.
