Two streetcar conductors whose streetcar is set to be dismantled sneak into the station late one night to take it for one last spin. They spend all night and most of the next day having small adventured throughout Mexico City. Agustin Isunza is the film's standout as an old man, Papa Pinillos, who worked for the streetcar company most of his life. He was laid off a while back, but he does little with his time besides get on random streetcars to see if their drivers are competent. When he jumps on the 133, he quickly realizes that it's stolen and he spends the rest of the film desperately trying to get the company to believe him. It's a fun movie and very charming. Not a necessary Bunuel film, but fans should certainly catch it. 8/10.
