Warner Bros. Pictures Animation and Warner Bros. Animation announce they are producing an original animated musical feature titled “Prehistoria,” with creator and animator Vivienne “VivziePop” Medrano. Deadline reports the project is intended for a theatrical release and frames Medrano as a leading independent animation voice emerging from YouTube creator culture. Polygon similarly reports that Warner Bros. announces the film at the Annecy festival and describes it as Medrano’s next project. Both outlets identify Medrano as the creative behind “Hazbin Hotel” and link her to the new musical film concept “Prehistoria.”

Across the reports, the key details that are consistent are the studio involvement, the project title, the nature of the film as an animated musical feature, and that the release is associated with Warner Bros. Animation’s slate. Neither source provides additional specifics in the provided text on plot, cast, production timeline, or release date, beyond the planned theatrical destination.
