Basketball superstar Jeremy Lin was moved to tears while watching "38 at the Garden," a documentary highlighting the "Linsanity" phenomenon that debuted at the Tribeca Film Festival on Tuesday. Directed by Frank Chi, "38 at the Garden" revisits Lin's cultural impact after he kicked off the "Linsanity" phenomenon. During the 2011-2012 NBA season, the former Taiwanese American athlete turned the New York Knicks' score around during a game against the Los Angeles Lakers at Madison Square Garden, scoring a total of 38 points.
