“Saturday Night Live” has been reflecting and influencing the American story for 40 years. Live From New York! explores the show's early years, an experiment that began with a young Lorne Michaels and his cast of unknowns, and follows its evolution into a comedy institution. Archival footage is interwoven with stolen moments and exclusive commentary from “SNL” legends, journalists, hosts, crew and others influenced by the comedy giant. Live From New York! captures what has enabled “SNL” to continually refresh itself over nearly 800 episodes and keep America laughing for 40 years.
