Elizabeth Lail is set to star as Anna while Scott Michael Foster will play Kristoff.
Once Upon a Time, starring Ginnifer Goodwin, Josh Dallas and Jennifer Morrison, follows characters from classic fairy tales who are trapped in the ‘real world’ fictional town of Storybrooke.
ABC is owned by Disney so the show has free rein when it comes to creating modern versions of the well-loved stories. The Frozen characters can expect to be rubbing shoulders with the likes of Snow White (Goodwin), Prince Charming, Captain Hook, Belle, Rumplestiltskin, Robin Hood, Peter Pan and Red Riding Hood.
Ellie is an entertainment, TV and film journalist writing news and (hopefully incredibly witty) comment for RadioTimes.com. She loves light-hearted dramas and glossy US series - and is more than a little bit obsessed with Downton Abbey. Foodie, sun-seeker and aspiring novelist in her own time. Likes the fact that her name rhymes with telly.
