A moody tale seemingly set in a dream-like past, Santiago Otheguy’s “La Leon” (2007) follows Alvaro (Jorge Román), a bookish fisherman in the remote Parana Delta in Argentina. His most common contact with the outside world is with “El Turu” (Daniel Valenzuela), the resentful, wary captain who ferries passengers from the island to the mainland each day. He’s sussed out Alvaro’s relationship with some of the visitors and suspects him of leading others astray. Wonder why that troubles the rough gentleman…? Beautifully shot in black-and-white, its restrained visual style suggests the asperity of Lisando Alonso’s work (“La libertad,” “Liverpool”) with a slightly less autistic attention to beauty of landscape and social interaction that is reminiscent of Julián Hernández’s memorable 2003 “A Thousand Clouds of Peace.” 85m.
