Well, it's only a pilot stage for now but it seems that the spin-off for Once Upon A Time, titled Once Upon A Time In Wonderland, set in a pre-cursed version of the place has already leaked some casting.
Sophie Lowe will be playing the role of Alice. The English-Australian born actress's previous roles have included All Saints, The Slap and Two Mothers but this will be her first leading role on a US television show if the five scenes due to be filmed in Vancouver is approved beyond a pilot for ABC's 2013-2014 TV schedule.
Elsewhere former Being Human actor Michael Socha has been cast in the role of the Knave of Hearts and like Lowe, this will be Socha's first leading role on a US television show. Also cast in the series, created by Edward Kitsis and Adam Horowitz is Peter Gadiot as Alice's mysterious love interest, Cyrus. It seems that format wise, this show will have a similar structure to American Horror Story, so this may be a one series only type of spin-off in intention, which is interesting.
Also cast in the newly renamed spin-off is Emma Rigby. The actress best known for her roles in Hollyoaks and Prisoners Wives will be playing the Red Queen, a rather short tempered ruler who is merciless towards those who betray her, especially her enemies. I have to admit while the casting pleases me so far for this spin-off, the renamed title is rather unimaginative, isn't it?
