Rivers aren’t the hottest environmental topic out there, but they’re unavoidable for most urban dwellers—especially in a water-crossed place like D.C. So give it up for the Environmental Film Festival’s decision to program a strong, uh, flow of river-oriented films this year. Beside the old reliables (Amazon, Mississippi), some other big shots (Rhine, Mekong, Ganges) will have their moments, too. And, of course, there are nods to the Anacostia and Potomac. The festival is bigger than ever, with 190 films showing at 50 different venues, and it retains its all-things-considered vibe. If flowing water isn’t your thing, there’s the D.C. premiere of Terrence Malick’s To The Wonder (shown); a John Huston in Africa series; the world premiere of Hot Water, which is actually about uranium mining; and The Fruit Hunters, about folks who look for exotic eats. Oh, and don’t forget about the animals: Meerkats, bonobos, falcons, ducks, otters, rhinos, and sea turtles all get star turns. Just leave the bottled water at home.

The D.C. Environmental Film Festival runs to March 24 at various venues. (202) 342-2564. See a complete schedule at dcenvironmentalfilmfest.org.
