It was 2001 when Paul Rudd, Amy Poehler, Bradley Cooper, Elizabeth Banks and about a million other soon-to-be-famous comic actors nobody had then heard of starred in a bad movie called Wet Hot American Summer.
The movie was about the high jinks of a group of teenagers on the last day of an American summer camp in 1981 and it probably would have sunk, never to be heard of again, had it not then been adopted and beloved by a generation or two of presumably deeply stoned American college students presumably high on nostalgia for their own summer camp years.
That adoption, combined with the growing famousness of the movie's cast meant it had enough commercial appeal 14 years later to generate a television series, in the form of a prequel, featuring the same movie characters.
The TV series still wouldn't have happened, however, had it not been for the emergence of Netflix. It's hard to imagine any other self-respecting broadcaster agreeing to take a risk on a series based on such a bad film, especially given that the cast had become exponentially more expensive in the interim. But, having taken that risk, Netflix found themselves with a 2015 hit.
