The "Black Freighter" releases also include "Under the Hood", a 38-minute, fictional in-universe documentary detailing the characters' backstories, which takes its title from that of Hollis Mason's memoirs in the comic book. Unlike the film and "Tales of the Black Freighter" which were both R-rated, "Under the Hood" is PG-rated because it is meant to resemble a behind-the-scenes television news magazine profile of the characters. The actors themselves were allowed to improvise during filming interviews in character. Bolex cameras were even used to film faux archive footage of the Minutemen.
