How Gravity Falls was made: Alex Hirsch, CalArts, and the 2010 pilot
The student film that became a pitch, the writing process Hirsch described in interviews, and the three studios that animated the series.
Gravity Falls started as an 11-minute student film. Alex Hirsch made it at the California Institute of the Arts, pitched it to Disney Channel on the strength of the short, and the channel bought it. That origin explains a lot about why the finished show feels unusually considered for a children's comedy, so it is worth setting out properly.
From CalArts to a Disney greenlight
Hirsch cited Twin Peaks and The X-Files as his primary non-animated influences, alongside animated sitcoms like The Simpsons. His stated takeaway from the latter was that animation could be funnier than live action, did not have to be only for kids, and could be satirical and observational and grounded in character interaction. He has said he turned down DreamWorks Animation executive Jeffrey Katzenberg at the time because he wanted to work at Disney.
After CalArts he was hired as a writer and storyboard artist on Cartoon Network's The Marvelous Misadventures of Flapjack, where he was paired with Pendleton Ward, later the creator of Adventure Time. He then co-developed Disney Channel's Fish Hooks and pitched Gravity Falls shortly before leaving. It was greenlit and premiered June 15, 2012.
The show is built on Hirsch's own childhood
The premise is autobiographical in a specific way. Dipper and Mabel's summer-camping structure comes from Hirsch's relationship with his own twin sister, Ariel, and Mabel is explicitly based on her. The setting draws on real Oregon roadside attractions, including the Mystery Spot and Oregon Vortex, plus the real town of Boring, Oregon. The fictional Gravity Falls, Oregon, is a composite of Pacific Northwest oddity tourism rather than a single real place.
Stan Pines is based on Hirsch's grandfather Stan, who by Hirsch's account told tall tales and messed with the kids to get a rise out of them. Dipper's compulsion to record and decode information comes from Hirsch's own memory of recording himself and playing it back to try to speak backwards, and Hirsch described himself as the kind of kid who carried sixteen disposable cameras everywhere. The characters the twins spend the summer with are, in Hirsch's framing, largely his own family and home town rendered into fiction.
The writing process
Hirsch described the pipeline in detail in interviews. An episode began as a synopsis in a writers' room, and dramatic structure was defined at that stage. A- and B-stories were handed to a writer for an outline, which Hirsch and creative director Mike Rianda checked off with feedback. The writer produced a draft, took further notes, and then Hirsch and Rianda would often rewrite a draft of their own before the final script, revising the dialogue heavily. Hirsch's own description of the final pass involves working all night before each delivery, in shifts.
The two structural choices Hirsch has talked about most are notable. He originally expected the show to run two or three seasons and had a beginning, middle, and end in mind before pitching it, but he wanted to end after season one on a cliffhanger because the workload was draining. Jon Stewart, whose children liked the show, and Over the Garden Wall creator Patrick McHale convinced him to return. The network only commissioned seasons in twenties, so a second season of twenty was the deal, and Hirsch's contract specified before he wrote it that season two was his last. That is why the voice cast and the story treat the finale as a conclusion.
Animation and studios
Production offices were at Disney Television Animation in Glendale, California. Episodes were animated by Rough Draft Korea, Digital eMation, and Yearim Productions. Sequences judged too important for the outside studios were animated in-house by storyboard artist and supervisor Dana Terrace. The score is by Brad Breeck, who also wrote the show's theme.
What the production history explains
Three things follow directly from this account. The ciphers are not set dressing, because the show was pitched from a short film built on a deciphering premise, which is why the cipher methods are all classical and solvable. The licensed tie-in books are unusually substantial, because a show that was finished on purpose got a closing publication line in Journal 3, Lost Legends, and The Book of Bill. And the real-world puzzle work, from the Cipher Hunt to the later terminal site, is the logical extension of a creator who has always treated the audience as participants rather than viewers.
