In February 2012, the New York Knicks were having a truly unremarkable season and seemed unlikely to see postseason play when a star emerged from their ranks -- Jeremy Lin, a point guard who sparked a seven-game winning streak that galvanized fans and gave the Knicks an unexpected shot at a playoff spot. While the Knicks' sudden turnaround seemed like something out of a movie, Lin was the unlikely hero -- a player of Taiwanese and Chinese heritage who was one of the few Asian-Americans playing in the NBA, and an athlete whose promising career had known more than a few setbacks, causing him to wonder if he might be cut from the Knicks' team before things finally clicked. Filmmaker Evan Jackson Leong had been following Lin's career before he became a fan favorite in early 2012, and in the documentary LINSANITY, he presents the full story of Lin's life on and off the court, including his relationship with his family, his college career at Harvard, his stint with the Houston Rockets, how he deals with racism in a sport where few Asians excel, and his strong Christian faith. LINSANITY received its world premiere at the 2013 Sundance Film Festival.
