"They became all of modern comedy." – Judd Apatow

When National Lampoon launched in the 1970s, there was nothing else like it. It began as a counter-culture magazine, but soon became a cultural institution in its own right, satirising authority figures and current events with an absurd, fearless approach that shocked the establishment. This documentary takes us on the unpredictable, wild ride of the Lampoon, from its successful film series to the creation of Saturday Night Live.

Featuring never-before-seen footage of rehearsals, radio recordings and their legendary 1973 show Lemmings, with young luminaries such as Bill Murray, Chevy Chase, John Belushi, Gilda Radner and Harold Ramis, it's an eye-opening and hilarious insight into the inception of one of America's most important comic institutions.
