Kin-dza-dza! (1986)

One winter evening, a Russian foreman named Vladimir and a Georgian student named Gedevan meet a strange man at the street, who claims to be stranded on Earth away from his home planet and shows them a teleportation device. Not knowing the odds, Vladimir and Gedevan press a random button on the device and end up on the planet named Pluke, where the advanced technology coexists with deserted wastelands, rusty exterior, tyrannical government and a rigid caste system. Now the two will have to get back home, getting acquainted with local customs and culture on their way.
