At 11:30pm on October 11, 1975, a ferocious troupe of young comedians and writers changed television - and culture - forever. Featuring an all-star cast as some of comedy's biggest names, Saturday Night tells the story of what happened behind the scenes during the ninety minutes leading up to the first broadcast of Saturday Night Live. Full of humour, chaos, and the magic of a revolution that almost wasn't, count down the minutes in real time until you hear those famous words.
