Core Announcement
Animator Vivienne Medrano, creator of *Hazbin Hotel* and *Helluva Boss*, will write and direct an original animated musical titled *Prehistoria*.

Pictures Animation (WBPA) will produce the film for theatrical release; no release date or cast details have been released.
Background
Medrano’s 2019 *Hazbin Hotel* pilot on YouTube later moved to Prime Video in early 2024, achieving the platform’s largest global debut for a new animated series. *Helluva Boss* launched on YouTube in October 2020 and shifted to Prime Video in September 2025. Her studio SpindleHorse has partnered with A24, Amazon MGM Studios, and Bento Box for *Hazbin Hotel*’s first season. WBPA President Bill Damaschke cites a strategy of working with creators who have strong direct-to-fan followings. Medrano is represented by CAA, Redefine Entertainment, and RLG.

Impact & Significance
*Prehistoria* is Medrano’s first theatrical feature, taking her work beyond the Hellaverse.

Conflicting Reports & Gaps
No cast, release date, or plot details have been released. Sources differ on whether the film will be rated “R” like *Hazbin Hotel*; the tone remains unspecified. Details on Medrano’s exact involvement amid her ongoing series commitments are absent.
