Zelena (Once Upon a Time)
In December 2013, Rebecca Mader was cast as the Wicked Witch of the West. She made multiple appearances during the second half of season three and was promoted to a series regular for the show's fifth season. The role of the Wicked Witch of the West was written specifically for Rebecca Mader. It was announced that the writers had chosen not to continue with Zelena's storyline and Mader would not be returning for the seventh season of the show. However, Mader later revealed that she would be returning for multiple season seven episodes.
Adam Horowitz
Horowitz and Kitsis created the ABC fantasy drama series "Once Upon a Time", which began airing on October 23, 2011. The show focuses on a town which is actually a parallel world populated by fairytale characters who are unaware of their true identity. The two came up with the concept seven years prior to joining the staff of "Lost", but wanted to wait until it ended before they focused on this project.
