Kevin Pollak did a fairly good job in asking and finding answers to the question, "Must a stand-up comic be miserable to be funny?" No, but it helps, as does a healthy dollop of both neuroticism and attention-seeking. Pollak interviewed comics, actors, writers, and directors for this, but some of his choices were off-base. Bobby Slayton, an angry comic and one of the hardest working stand-ups over the past 35+ years, gets very little screen time (it would have been interesting to hear how he developed his persona, even in bonus material). Chris Rock, Louis C.K., Jerry Seinfeld, and Ricky Gervais would have been natural fits, but none of them were in the film.Of all the very funny female stand-ups, he only interviewed Maria Bamford and Whoopi Goldberg, and gave excess screen time to women who serve as prima facie evidence for "women aren't funny," such as Janeane Garofalo and the utterly boring Kathleen Madigan (in fairness to Garofalo, she used to riff really well on panel shows, but she never could sustain a set without serious dead space), omitting Lisa Lampanelli, Rita Rudner, and Elayne Boosler, and coming too late to interview Joan Rivers. There was also too much time given to Amy Schumer, who actually used to be funny before she became as big a joke thief as Carlos Mencia, but everyone backed off of her because of her sex, and the time spent on Mitch Hedberg's widow was a total waste of film since Hedberg could only be funny to the perpetually stoned, also the same market for the Grateful Dead. George Carlin's daughter was interesting in terms of exposing a side of Carlin I never knew about.
