As for the One Piece Film: Strong world movie, we have decided to make the movie fully canon. It has been confirmed that Oda considers the events of the movie as
the actual events that take place in the story in SBS Volume 55, stating that the events of the movie are true to the manga in his artbook for the movie. Oda has also placed the main villain's antagonistic relationship with Luffy
in his databook, One Piece Blue Deep: Characters World, which specifically only captures canon information, stating that they are enemies, when this relationship has only been built in the movie. It fits perfectly in the timeline from the middle of Thriller Bark and Sabaody Archipelago. The issue of Brook's "contradicting statement" has been accepted as a retcon to the story, as the movie was created a year and a half after the statement. It was decided
in this thread.
