Remember, in Gravity Falls, there is no one you can trust."
Gravity Falls is an animated Disney Channel Original Series created by The Marvelous Misadventures of Flapjack alum Alex Hirsch and produced by Rob Renzetti. The first episode was shown on June 15, 2012, as a "sneak peek", though the show didn't officially premiere until June 29, 2012.
For one whole summer vacation, twins Dipper (Jason Ritter) and Mabel Pines (Kristen Schaal) are visiting their great-uncle Stan (Hirsch) in the valley town of Gravity Falls, Oregon, where he owns the Mystery Shack, a tourist trap operating as "the world's most bizarre museum". Dipper and Mabel's situation worsens (or rather, improves) when Dipper finds a mysterious book, the cover bearing an insignia of a six-fingered hand marked with the number "3". Upon opening it, he discovers that it is a Great Big Book of Everything, explaining the many strange beings, past events, and even federal cover-ups that exist within this town of secrecy.
Thus begins Dipper and Mabel's adventures as they interact with the supernatural world that surrounds them, all while following a Myth Arc where Dipper tries to find the journal's mysterious author.
After the Season 1 finale, the series went on a year-long hiatus. Several mini-series of short films were released over the break to keep fans content. Season 2 premiered on August 1, 2014, a year after Season 1 ended. The series was rebranded as a Disney XD original series, with episodes premiering on that network first before airing later on Disney Channel. In November 2015, Alex Hirsch announced that Season 2 would be the final season, with the Grand Finale airing February 15, 2016, as a one-hour special. Hirsch has since stated he remains open to the idea of continuing the series with additional episodes or specials, and he delivered with the defictionalized book Gravity Falls: Journal 3 and the comic book anthology Gravity Falls: Lost Legends.
A DVD/Blu-ray of the complete series was released on July 24, 2018, from Shout! Factory, making it the first Disney animated series to receive such a release. In March 2023, the box set was discontinued.
