“Saturday Night Live” compatriots Fred Armisen, Bill Hader, and Seth Meyers serve as creators, executive producers, and writers of this IFC original series, using their love of documentary films and combining it with comedy to present a unique take on the form. Hosted by Dame Helen Mirren and starring Armisen and Hader, each episode is shot in a different documentary film style, paying tribute to some of the most important stories that didn’t actually happen. “SNL” creator Lorne Michaels also executive produces “Documentary Now!”, and guest stars include Jack Black and John Slattery.
