Three of these movies had shorts accompanying them: The Adventure on Clockwork Island with Jango's Dance Carnival, Chopper's Island of Strange Animals with Dream Soccer King, and The Curse of the Sacred Sword with Take Aim! The Pirate Baseball King.

These four movies all carry the subtitle 'One Piece Film'. Oda would also be heavily involved in movies 12, 13, and 15, for which he is credited as 'general producer' ( 総合プロデューサー, sōgō purodyūsā ?). For the first nine movies, Eiichiro Oda was not involved in the films any more than other anime projects This changed with the production of movie 10, for which Oda wrote the story and served as executive producer. Most of the movies have completely original stand-alone plots set broadly around the contemporary story arc, but movies 8 and 9 directly adapt storylines from the manga. After the third movie (released in 2002), Toei discontinued the fair, and all subsequent movies were produced as standalone features (with the exception of the eleventh movie, released as a double feature with Toriko 3D Movie: Kaimaku! Gourmet Adventure!! for Toei's 2011 'Jump Heroes' event).

Initially, these movies were released annually as part of Toei's springtime 'Anime Fair' events, always as a double feature with various Digimon films. While generally made with the same cast and crew as the TV anime, they tend to boast much higher production values and animation quality. The One Piece Movies are theatrical films produced and released by Toei Animation. For other uses of this name, see One Piece (Disambiguation).
