What would President Donald Trump’s “big beautiful wall” do to the beauty of the Rio Grande and its Valley?  And what would the wall do to the lives of the people, animals, even insects who live very interdependently there?  A new documentary, The River and the Wall, directed by Ben Masters, maker of the excellent Unbranded shows you the answers.  Hillary Pierce produced the film and made the trek downriver by bicycle, mustang and canoe, from El Paso to the Gulf of Mexico.
