Jessica Biel and Justin Timberlake are preparing for a South Park-themed family Halloween on October 31, 2026. The couple and their two children, Silas and Phineas, will utilize the show's winter-themed character costumes.

The family resides in Big Sky, Montana, where they must travel to nearby suburban neighborhoods to trick-or-treat. Their costume strategy relies on winter apparel to accommodate the region's climate.
