Trivia / Doraemon: Nobita's Treasure Island

• Milestone Celebration: Was released on the 20th Anniversary of Doraemon: Nobita's Great Adventure in the South Seas, the previous pirate-themed adventure.
• What Could Have Been: The movie was originally conceived as a remake of Doraemon: Nobita's Great Adventure in the South Seas, much like the remakes of Doraemon: Nobita's Dinosaur, Doraemon: The Record of Nobita : Spaceblazer, Doraemon: Nobita and the Haunts of Evil, Doraemon: Nobita's Great Adventure into the Underworld, Doraemon: Nobita and the Steel Troops and Doraemon: Nobita and the Birth of Japan that came before it. The script was retooled into an original story halfway through production.
