Alex Rivera swept up awards at Sundance in 2008 with his socially-conscious sci-fi film, Sleep Dealer, a dystopian look at the future of Mexican/United States border control. Since then, the filmmaker has taken his time assembling a follow-up. This week, Rivera earns the title of programmer and artist-in-residence for Tales from Planet Earth, a science- and environment-themed festival beginning Nov. 1 at the University of Wisconsin-Madison. In its seventh year, Tales from the Earth culls films from across the globe, ranging from factual documentary to speculative future fiction.
