On the current season of Weeds, the brother-in-law and erstwhile accountant of pot-dealing MILF Mary-Louise Parker hatch a moneymaking scheme they're convinced can't miss: becoming "coyotes," guiding illegal immigrants across the US-Mexico border. Weeds is, of course, a comedy, but its characters' recent relocation to the San Diego area has made border-crossing (Parker drives across to pick up a shipment ... ) and immigration ( ... and, unknowingly, brings back a man in the trunk of her Prius) among the show's focal themes. The same topic, but from a (mostly) more serious angle, informs "Crossing the Border," a film series running Aug. 15–21 at the Roxie Film Center. Joseph Mathew and Dan DeVivo's 2006 doc Arizona Crossing takes a sobering look at immigration via the harsh, remote, and often deadly Southwestern desert, offering revealing interviews with both advocates and opponents. Of course, US-Mexico ain't the only high-tension border on the globe. "Crossing the Border" is cosponsored by Goethe-Institut of San Francisco, and many of its selections concern European frontiers — proof that the desire to find a better life (even if it involves a total uprooting of all that is familiar, and introduces almost certain danger) is truly a universal one.
