candidates: In February 2013, Kitsis & Horowitz, along with producers Zack Estrin and Jane Espenson, developed a spin-off focusing on Lewis Carroll's "Wonderland". The series was given the proposed title "Once Upon a Time in Wonderland". A "teaser presentation" began shooting in April 2013, with the pilot being shot in late July or August. On May 10, 2013, ABC announced that it had green-lit the spin-off and on May 14, 2013, announced that the spin-off would air in the Thursday night 8:00pm time slot instead of making it a fill-in for the parent series, which had been hinted in the early stages. The series premiered on October 10, 2013, for a thirteen-episode run that will end on April 3, 2014.
