Gwen and Rhys are a Welsh-speaking couple living in Cardiff where Rhys works as a photographer and Gwen is employed as a historical interpreter at a local Welsh cultural centre. Gwen is also an aspiring actress and although she periodically attends auditions, she has yet to be hired for a theatrical part. The couple's inability to conceive a child has caused increasing tension between them. Hoping to reinvigorate their relationship, the pair decide to travel together to southern Argentina where Rhys has been commissioned to photograph the :es:Anexo:Capillas Galesas del Valle inferior del río Chubut|historic Welsh chapels in Patagonia, a vast windswept landscape which was a destination for Welsh immigrants in the late 19th and early 20th centuries. While there, they are served by their local Welsh-Argentine guide, Mateo. Meanwhile, an elderly Welsh-Argentine woman named Cerys is planning a trip to Wales to discover the farm where her mother was raised before emigrating to Patagonia during the 1920s. She decides to take along her agoraphobic young neighbour Alejandro to assist her. In Wales, he finds romance with a local girl, Sissy.
Matthew Rhys found out about the role under unusual circumstances. In 2005, he was in Patagonia on horseback with descendants of the region's original Welsh settlers; during the trip, he met director Marc Evans, who was there scouting for locations.
Reception
Following a screening at the 2010 Mill Valley Film Festival, Dennis Harvey of Variety said "Patagonia unspools two parallel narratives connected only by a historical anomaly.... While its separate parts may not quite add up, they complement each other quite pleasingly." He also notes "Evans nimbly cuts between the two unhurried threads, which form a nice textural contrast in d.p. Robbie Ryan's lensing of the disparate landscapes—one all lush, verdant hills, the other rich in desert hues. Jumping back and forth also helps balance out stories that might have seemed insubstantial if each stood alone." Another critic at Mill Valley, Sura Wood of The Hollywood Reporter, called it an "intermittently divertingroad movie, whose alternation between parallel storylines grows tedious over the course of its two-hour running time"; Patagonia is "somewhat redeemed by gorgeous cinematography of far flung locations not often seen in movies, and fine performances from its cast." The Independent described it as "two road movies for the price of one, running the parallel stories of pilgrims on a search for identity"; the film is "wonderfully shot by Robbie Ryan " and "displays a lyrical sensitivity both to the desert landscapes of Patagonia and to the remote, rain-glazed hills of Wales, and the unlikeliness of their ancient connection becomes rather moving."
