Cantwell also provided the technical dialogue for the 1977 film Close Encounters of the Third Kind and designed the computer graphics for the 1983 film WarGames. In addition to the creation of the Death Star, Cantwell contributed to the designs for the X-Wing, TIE fighter, and Star Destroyer.

Cantwell’s passion for space made him one of the greatest designers of Sci-Fi spaceships. He went on later to write two science fiction novels, CoreFires 1 and Corefires 2. His wife Sierra Dall said that her husband had Alzheimer’s Disease in the final years of his life.
