After "Semi-Tough"'s release in 1977, Bert Convy was contacted by a number of est followers, as well as by Werner Erhard. After Convy appeared on "The Tonight Show" and discussed his experiences attending Erhard Seminars Training in preparation for his role as Friedrich Bismark, he received a letter from Erhard stating: "it would be great for us to get together". Of the est seminar itself, Convy recalled that when another attendee complained of a headache during the course, the group leader told him to "experience it", and when another attendee wet his pants, he was told to "experience the warmth". In a scene from the film, a woman exclaims to Friedrich Bismark in the middle of a seminar: "I peed in my pants and it felt "good."" During actual filming on "Semi-Tough", Convy received a late-night phone call from actress Valerie Harper, known in Hollywood as a devoted student of Werner Erhard. She related to Convy that Erhard was "pleased" with the role, and she wished him success in the film. Convy suspected that her real reason for calling was to subtly pressure him to go easy on his parody of Erhard in the film. Harper is mentioned by name in the completed film.
