Once Upon A Time has added to their cast for Season 4. As most people already know, Frozen is coming to Storybrooke -- and more actors have now been confirmed for some new adventures. According to E! Online, Shameless star, Tyler Jacob Moore is the most recent OUAT addition. Moore will be playing (wait for it) Hans -- and you have to admit, he totally looks the part! Moore will be joined by actress Georgina Haig (Elsa), Elizabeth Lail (Anna), and Greek actor Scott Michael Foster (Kristoff).

Oncers have also learned that Lost star Elizabeth Mitchell will be on Season 4, playing Anna and Elsa's mother. According to Variety, John Rhys-Davies will be the voice of Pabbie, the rock troll.

"The character, voiced by Ciarán Hinds ('Game of Thrones') in the Disney mega-hit, is first tasked with 'curing' young Anna after Elsa accidentally freezes her head with her icy magic."

Also confirmed for the new season is actor Michael Socha, who will bring The Knave Of Hearts from Once Upon A Time In Wonderland to Storybrooke. Everyone is excited to see where the writers are going to take the plot -- and what twists and turns will be in store.

As previously reported by The Inquisitr, the OUAT panel at Comic-Con was understandably popular. There was a special Season 4 trailer that was shown and has since been uploaded to YouTube so that Oncers unable to travel to San Diego can also take a peek at the teaser (check it out below). While it's still unclear how the Frozen cast is going to fit into life in Storybrooke, other plots seem more obvious. You know, like Hook and Emma's relationship. The two will likely get close, since Emma's previous love interest (Neal) was killed off.

Once Upon A Time returns to ABC on Sunday, Sept. 28. Are you excited for the new season?
