Here's a fun video essay from Turner Classic Movies about sci-fi movies that are regarded as "camp". The emphasis is on some obvious choices: "Plan 9 from Outer Space", "Queen of Outer Space" and "Barbarella"- but it also covers the lesser known cinematic disaster, "The Apple". The video addresses the debate over whether a film can be intentionally designed as "camp" or if that designation only comes about as an unintentional consequence.
