Once Upon a Time season 7

The seventh and final season of the American ABC fantasy-drama series Once Upon a Time was ordered on May 11, 2017. It premiered on October 6, 2017, and consisted of 22 episodes, having aired on Fridays instead of Sundays in prior seasons.

The season marked a significant change for the series, as it was announced at the end of the sixth season that the majority of the main cast members would not be returning in such capacity for the seventh. Lana Parrilla, Colin O'Donoghue and Robert Carlyle were the only ones remaining, while Rebecca Mader and Jared S. Gilmore returned in recurring capacities. Andrew J. West and Alison Fernandez were announced as new regulars in May 2017. Dania Ramirez and Gabrielle Anwar were announced as additional regulars in July 2017. In August 2017, it was announced that Mekia Cox had been promoted to series regular after initially joining the cast in July as recurring.

The storyline was softly rebooted  with a main narrative led by an adult Henry Mills, set several years after last season's events. In February 2018, it was announced the seventh season would serve as the final season of the series; the season and series concluded on May 18, 2018.

Existing fictional characters introduced to the series during the season include Tiana, Mother Gothel, Eudora, Dr. Facilier, Prince Naveen, Madame Leota, and Captain Ahab. The season also introduced new iterations of various characters from previous seasons, including Cinderella, Lady Tremaine, Drizella, Anastasia, Rapunzel, Jack, Hansel, Gretel and the Blind Witch, as well as Alice, another version of whom previously appeared in Once Upon a Time in Wonderland.

Premise
Several years after the final battle, Henry Mills leaves Storybrooke in search of his own story, only to find himself in the Magical Kingdom, where a conflict among its inhabitants culminates in the casting of a new curse that sends the Magical Kingdom inhabitants to a Seattle neighborhood known as "Hyperion Heights", and back to the past, before Henry left Storybrooke. As Henry's daughter Lucy sets out to restore his belief, Mother Gothel seeks to reclaim her former home by using her Coven of the Eight, while other villains, including Lady Tremaine, Drizella, Dr. Facilier, and Hansel, each have their own agendas. The eventual breaking of the curse leads to the arrival of the Wish Realm version of Rumplestiltskin, who seeks to destroy everyone’s happiness. His defeat leads Regina to cast a good variation of the Dark Curse, which merges all the realms into one: the United Realms.

Development
In January 2017, while the sixth season was still in production, ABC president Channing Dungey spoke of a possible "reset" of the show's narrative in the event that the show received an order for a seventh season. After much speculation, executive producers Adam Horowitz and Edward Kitsis later confirmed that certain characters would have their storylines wrapped up and that the back-end of the sixth season had been written with season seven's narrative change in mind. Despite the major changes from seasons past, the showrunners have said that they do not view season seven as a complete reboot of the show. Horowitz said: "I hesitate to use the word 'reboot'. We're more thinking about it as a hybrid of a lot of things. We're paying homage to the original premise, but there are certain characters who are returning and some who are not. It's a combination of a lot of things, but what we're trying to do is go in a new direction but stay true to the spirit of what the show has always been."

In July 2017, the creators announced that the season would be set in the fictitious Seattle neighborhood of Hyperion Heights, which was created under a new curse. Residents of this neighborhood included displaced characters from the original and new versions of the Enchanted Forest, as well as regular people from the Land Without Magic. This differs from Storybrooke in the first six seasons, which was an isolated town that was blocked off from real-world Maine. The initial villain is Lady Tremaine, who assumes the role of an urban developer who seeks to "gentrify the neighborhood" and push out and separate fairytale residents. Meanwhile, Storybrooke and various Fairy Tale Land locations still appear in the flashbacks of the season as the story bounces back and forth between the characters' lives before and during the latest curse.

The main flashback setting of the seventh season is the New Enchanted Forest, which is a New Fairy Tale Land realm. Other locations featured in flashbacks are the Edge of Realms, the Wish Realm, the New Wonderland, Oz, and Storybrooke.

Casting
In May 2017, it was announced that Lana Parrilla, Colin O'Donoghue, and Robert Carlyle would be the only series regulars from season 6 to continue onto season 7. The character of Henry would also return, but as a man in his late 20s-early 30s portrayed by Andrew J. West. It was teased that the four would be portraying their original characters but with cursed identities, similar to the circumstances in season 1. In July, the first promo of the season revealed that Killian is now a Seattle police officer with the last name Rogers, who is living with an unexplained sense of loss. In August, it was revealed that Regina is now a bar owner named Roni, who is more dressed down and is "no longer in charge."

Former main cast member Jennifer Morrison has confirmed that she has agreed to return for at least one episode, first appearing in the second episode of the season. Morrison announced her last filming day for the episode on July 19, 2017. On July 22, it was confirmed that Emilie de Ravin would return for the fourth episode of the season.

In March 2017, Andrew J. West and Alison Fernandez were cast for unknown guest roles in the season 6 finale.

It was later revealed that the character would appear in a multi-episode arc. On September 20, it was announced that former regular Rebecca Mader would return for multiple episodes in the seventh season as Zelena, who would also have a cursed identity.

On October 2, it was announced that Dr. Facilier from The Princess and the Frog would make an appearance during the season, later revealed to be portrayed by Daniel Francis in the season's fifth episode.

On March 16, it was announced that multiple former cast members were set to appear in one or both of the season's (and series') last two episodes.

On March 21, it was announced that Morrison and de Ravin would be back for a second time, along with Ginnifer Goodwin and Josh Dallas for the final episode of the series. In addition, Raphael Sbarge, David Paul Grove, and Faustino Di Bauda confirmed that they would also appear in the finale.
