The Wizards Beyond Waverly Place finale arrives all at once — four episodes that close out the series, airing on Disney Channel on August 4 at 8 p.m. ET/PT and landing on Disney+ the next day, August 5 (Deadline).

Disney+ press materials give the finale event its own title: "One Last Spell," labelled as Season 3 in a press release dated April 2, 2026 (Disney+ Press). TVLine separately identified the same four-part event as Season 3 and confirmed the August 4 air date (TVLine). The most recent Deadline feature, published August 3, refers to the four episodes as Season 2 (Deadline). The discrepancy in season numbering aside, the key facts line up: four final episodes, same premiere dates, same streaming window.

Selena Gomez makes her directorial debut with the first episode — a first for the actor and singer who originated the role of Alex Russo in the 2007–2012 Disney Channel series Wizards of Waverly Place, created by Todd Greenwald (Deadline). Gomez also reprises Alex on-screen across multiple episodes of the finale.

David Henrie returns as Justin Russo, now training three young wizards for the Family Wizard Competition after his sons Roman and Milo gain magical powers. The cast includes Janice LeAnn Brown as Billie, Alkaio Thiele as Roman, Max Matenko as Milo, Taylor Cora as Winter, and Mimi Gianopulos as Giada Russo (Deadline).

The finale brings back several familiar faces. Jennifer Stone reprises Harper Finkle, Gregg Sulkin returns as werewolf Mason Greyback, and Maria Canals-Barrera guests as Theresa Russo, mother of Alex and Justin. Brandon Micheal Hall joins as Damien Penwulf, Billie's father — a character central to the finale's story, in which Billie, still reeling from losing Alex, discovers that rescuing her mother requires reuniting with her long-lost father (Disney+ Media Kit). Ramon Reed plays Silas Evilini and Tobias Jelinek plays Lord Morsus (Deadline).

The first season of Wizards Beyond Waverly Place ran 21 episodes — meaning this four-part finale is a notably shorter run to close the story (Deadline). Disney+ released an official trailer for the finale event on July 15, 2026, offering a first look at the returns of Harper and Mason (Disney+ Press).

Jed Elinoff and Scott Thomas serve as writers and executive producers, alongside executive producers Gary Marsh, Jonas Agin, Rick Williams, Selena Gomez, and David Henrie (Deadline).

For fans who grew up with the original series, "One Last Spell" gathers nearly the entire Russo family circle for a final round. The writers' room and crew of roughly two hundred that built this revival now have their ending — four episodes, one night on linear, one day later on streaming.
