Fan Casting Gravity Falls: The Movie (2025)

When 12-year-old twins Dipper and Mabel Pines are sent to spend the summer with their eccentric great-uncle Stan in the remote town of Gravity Falls, Oregon, they expect boredom and chores. But that all changes when Dipper discovers a mysterious journal in the woods — one filled with secrets, cryptids, and coded warnings of danger. As the twins unravel Gravity Falls’ bizarre history and supernatural activity, they team up with teenage slacker Wendy, lovable handyman Soos, and the ever-suspicious Grunkle Stan. But lurking behind the town's weirdness is a powerful entity from another dimension: the triangle-shaped trickster Bill Cipher — voiced by original series creator Alex Hirsch. Reality begins to unravel, secrets come to light, and the fate of the world could rest on the shoulders of two kids who just wanted a quiet summer.
