Intrigued by Sound of My Voice, the clever Sundance thriller now in select theaters starring Brit Marling as a cult leader who claims to be from the future? Lucky for you, Vulture is giving away twenty pairs of tickets to see the movie in New York and Los Angeles! (And it's a run-of-engagement offer, so they're valid during the whole theatrical run of the movie.) To enter, entrants must follow @Vulture on Twitter and retweet one of two phrases: "Hear the Sound of MY Voice, @Vulture, and pick me to win tickets! #soundofLA” or “Hear the Sound of MY Voice, @Vulture, and pick me to win tickets! #soundofNY," depending on which city you’re vying for. The contest runs today from 2 to 4 p.m. ET (noon to 2 p.m. PT), so send us your tweets between then. If you win, we'll announce it on Twitter and then DM you with the details. (You can check out additional rules here.) Good luck!
