Trailer released for 'The River and the Wall,' SXSW prize-winning film about Rio Grande and Trump's border wall

Film by Ben Masters features commentary from Democratic presidential contender Beto O'Rourke

There has been no shortage of rhetoric around President Trump's signature campaign promise--to build a wall across the entire U.S.-Mexico border. What there has been a lack of is actual information about the impact of a wall were it to be built, and insight into the terrain it would cover. In the absence of that, the wall has remained a convenient slogan for Trump, an "idea" whose practicality was always beside the point.

The new documentary The River and the Wall, directed by Ben Masters, explores the rugged country in question. The filmmaker set out with a group of friends to navigate the Rio Grande along the Texas-Mexico border and to talk with those most directly affected by immigration and the proposed wall. 

The film, which premiered at SXSW where it won the Louis Black "Lone Star" Award, opens in theaters May 3. In anticipation of that a trailer has dropped. Watch it below.
