Spaced Invaders (1990)

A group of bumbling Martians misinterprets a radio airing of Orson Welles' "War of the Worlds" as an actual invasion of Earth. Convinced they must intervene, they crash their malfunctioning spacecraft in a small American town. Coincidentally, their arrival aligns with Halloween, leading the locals to mistake them for costumed children. Chaos and hilarity unfold as the clueless aliens struggle to assert their authority while navigating the confusion of a festive night filled with tricks and treats.
