The Last Starfighter is a 1984 science fiction adventure film directed by Nick Castle. The film tells the story of Alex Rogan (Lance Guest), an average teenage boy recruited by an alien defense force to fight in an interstellar war. It also featured Dan O'Herlihy, Catherine Mary Stewart, Robert Preston, Norman Snow and Kay E. Kuter.
The Last Starfighter, in addition to Disney's Tron, has the distinction of being one of cinema's earliest films to use extensive computer-generated imagery (CGI) to depict its many starships, environments and battle scenes. This CGI technique, for the time, was a great leap into the future compared to contemporary films such as the previous year's Return of the Jedi, which still used static physical models shot by moving film cameras.
