What is the English title of the first Pokémon animated feature film released in 1998?

The English title of the first Pokémon animated feature film is Pokémon: The First Movie.

The film was released in Japan on July 18, 1998, under the title Mewtwo Strikes Back. Its story centers on Mewtwo, a genetically engineered Pokémon who invites trainers to New Island and challenges ideas about identity, creation, and the relationship between humans and Pokémon.

The English-language release arrived in North America and other territories in November 1999. International marketing used the title Pokémon: The First Movie, while the subtitle “Mewtwo Strikes Back” identified the main feature in many listings. This creates a common naming mix-up between the film’s English title and its Japanese title.

The theatrical release also included the short Pikachu’s Vacation in many markets. A full computer-animated remake, Pokémon: Mewtwo Strikes Back—Evolution, followed in 2019, but it is a separate film rather than the original feature.
