Treasure Planet took roughly four and a half years to create, but the concept for Treasure Planet (which was called Treasure Island in Space at the time) was originally pitched by Ron Clements in 1985 during the meeting wherein he and John Musker also pitched The Little Mermaid.
Treasure Planet tager alt i alt 4½ år at lave, men selve konceptet for Skatteplaneten (som blev kaldt "Skatteøen i rummet" på tidspunktet) blev allerede lagt frem af Ron Clements i 1985 under et møde, hvor ham og John Musker også fremlagde ideen om Den lille Havfrue.
