When the description calls this a 'dark comedy' it ain't kidding. We begin with an opening scene of a guy preparing to blow his brains out. The film progresses through alcoholism, infidelity, assault & battery, douchebags, sleazy entertainment suits, guns, more alcoholism, irreverent Mexican stereotyping, more guns, and more people about to blow their brains out. Call me sick, but I laughed the whole way.
Despite these sensational events, this is a very character-driven story, and its minimal presentation (the whole movie basically happens on a guy's balcony) reminds me of a cleverly written play or slick British comedy. If you liked "Death at a Funeral" (original British version) or "Le dîner de cons" (original French version) or maybe even the classic "Arsenic & Old Lace", I think you'll enjoy this flick. The common theme of all these films being: a whole bunch of certifiably insane characters are stuck together for 90 minutes. Throw in a few guns and you got a laugh riot on your hands.
Beyond laughs, though, this film has some compelling themes going on. In particular the title "My Tiny Universe" implies just what it sounds like. For a brief afternoon, a seemingly insignificant loser's life attracts a menagerie of mighty & powerful people, all of whom find themselves irrevocably sucked in to a black hole of events. We see a group of incompatible people who are ironically drawn close by the common misery of having the worst day of their lives. It makes you realize that the universe isn't as big as it seems, nor is it exclusive. Thumbs up to great writing, great directing & great performances all around.
