Disney executive Meredith Roberts shares a surprising update on Gravity Falls, eight years after the series finale. Created by Alex Hirsch, the 2012 animated show was centered around Dipper and Mabel Pines, young twins who explored the mysterious town of Gravity Falls, Oregon and assisted their great-uncle Stan. Along with Hirsch, who portrayed Stan and other characters, the voice cast of Gravity Falls included Jason Ritter, Kristen Schaal, Linda Cardellini, and J.K. Simmons. Despite a large fanbase on Disney Channel, the series ended prematurely after season 2.
