Spaced Invaders is a 1990 science fiction comedy directed by Patrick Read Johnson and starring Douglas Barr, Royal Dano and Ariana Richards.
The space armada from Mars, known as the Imperial Atomic Space Navy (Battle Group Seven), fights an interstellar war against their long-time enemy, the Arcturans. The armada is forced into battle by Enforcer Droids, tasked to keep the Martian soldiers in line. Meanwhile, an incompetent crew of a small Martian spaceship, from the Civilian Asteroid Patrol, intercept a distress signal from the fleet, followed by a Halloween rebroadcast of Orson Welles' 1938 The War of the Worlds radio dramatization.
Mistaking this for a real invasion and not wanting to miss out on the glory, they land their ship in the tiny community of Big Bean, Illinois and begin their invasion of Earth. The ship's smart-mouthed pilot, Blaznee, with more common sense than the others, doesn't think it's a good idea, but he is ignored: Captain Bipto, the overzealous optimist of the group; Lieutenant Giggywig, the ambitious, know-it-all hothead; Dr. Ziplock, the careful and calculating scientist; and Corporal Pez, who is overeager, yet timid. They search for the invasion fleet
