"We're excited to be using these fairy tales that people are very familiar with, but we'll also be excited to open them up in a way that people have never considered them," said actress Jennifer Morrison.
Characters including Snow White, Prince Charming, the Evil Queen and Rumplestiltskin, and they all come together in a show that mixes a bit of magic with a bit of reality.
"It really does have a little everything while being original. There's a little 'Harry Potter,' a little 'Twilight,' a little 'Pushing Daisies,' a little 'Lost,' but at same time, still something really, really unique, and we all had the same reaction when we saw the pilot, which is there's really nothing like this that's ever been on television," said actress Ginnifer Goodwin.
Morrison said that while the show has a lot of mythology, it's still grounded in characters who are real people and have real relationships that viewers will be able to connect with.
"I think it will inspire people. Just reading and being a part of these scripts has inspired me to be like, 'Don't let go of those dreams,'" Morrison said.
"Once Upon A Time" debuts Sunday night at 8 p.m. on ABC7.
