Simon Pegg is the only original Ice Age cast member to reprise his role.
This is the first "Ice Age" film or short in which Scrat doesn't make an appearance. Similarly, it's the first film not to feature the involvement of "Ice Age" creator, original director and Scrat voice actor Chris Wedge. The former instance was due to Disney losing the rights to the character in 2020 after a longtime legal battle with designer Ivy Supersonic. The legal rights were subsequently resolved, as a series revolving around the character, titled La era de hielo: Las aventuras de Scrat (2022), was announced soon after.
The first Ice Age film to not be produced by Blue Sky Studios. The film was instead animated by Bardel Entertainment.
The project was originally intended as a Disney+ series before being changed into a feature film for the same platform.
Due to budgetary limitations, a majority of the principal characters were recast.
