What exactly is “Sleep Dealer”? It’s a new science fiction movie from Mexico, directed by Alex Rivera from a script by David Riker. The film has been making waves on the festival circuit, thanks in part to its timely and politically motivated storyline. The film stars Leonor Varela, most well-known to genre fans from “Blade 2″ and other Hollywood movies, and Jacob Vargas, and uses its sci-fi content as an allegory for today’s political climate vis-a-vis the immigration issue and other topics.
