The Last Starfighter (1984)

Description

Millions of light-years ago, a great frontier was constructed in the universe to protect the Star League of Planets from its enemy, the evil KO-DAN. But now a defector has given the key to the frontier to the KO-DAN, and Starfighters from throughout the galaxy are needed to defend the peace. One recruiter, the alien scalawag Centauri (Robert Preston), visits Earth to fill his quota of recruits and finds Alex (Lance Guest), an 18-year-old Earthling with an extraordinary talent for video game wizardry. Alex is quickly propelled into the regions of outer space to join others from planets throughout the Star League to fight a war to save the universe.
