They Live

They Live (1988) is a John Carpenter-directed sci-fi horror film where a drifter (Roddy Piper) discovers special sunglasses that reveal aliens are secretly controlling humanity through subliminal messages in media and advertising, leading him to fight back against the invaders. Initially receiving mixed reviews, it has since become a cult classic, praised for its social commentary on consumerism and conformity, and is known for its iconic lines and long fight scene. 

Galaxy Quest

Galaxy Quest (1999) is a sci-fi comedy about the washed-up cast of a beloved 1970s sci-fi show, Galaxy Quest, who are mistaken for real heroes by an alien race that has intercepted their show as historical documents and beams them aboard their spaceship to fight a real enemy. The actors, led by Tim Allen, Sigourney Weaver, and Alan Rickman, must improvise their roles to save the aliens, who believe the show's fictional adventures are real. Directed by Dean Parisot, the film is a loving parody of sci-fi fandom and tropes, released on December 25, 1999.
