Hugh Hefner: Once Upon a Time is a documentary about the life and times of Hefner, the publisher of the legendary men's magazine Playboy, and how he changed the sexual climate of America. Though it was made with the cooperation of Hefner and Playboy Enterprises, the documentary doesn't gloss over the scandals that besieged Hefner and his business during the '50s, a feature that makes Once Upon a Time a surprisingly effective and detailed documentary.~ Stephen Thomas Erlewine, All Movie Guide
