Adam Horowitz (born December 4, 1971) is an American screenwriter and producer. He is best known for co-creating the ABC fairy tale drama series Once Upon a Time with his writing partner, Edward Kitsis.
After graduating, Kitsis and Horowitz traveled together to Los Angeles, and worked together on Fantasy Island, Felicity and Popular, before joining the Lost team halfway through the first season. He is married to Erin Barrett 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.[8][9]
Kitsis and Horowitz also worked on the first four episodes of Tron: Uprising. He explains that he has used this chance to explore the Tron universe, particularly the life of a program under CLU's regime.[10]
Kitsis, Horowitz, and Josh Gad will serve as creators and writers for a limited prequel series to Disney's 2017 film Beauty and the Beast.[11] The series was conceived after the three had a discussion after the cancellation of their planned Disney+ series, Muppets Live Another Day.[11] In December 2019, it was announced that Horowitz and Kitsis were working on a new TV show set in the world of fairy tales and Disney titled Epic.[12] The pilot was picked up by ABC in January 2021, however it was dropped in August of the same year.[13]
