Bernstein and Ritchie's modified screenplay based on Jenkins' book includes a storyline with "satiric jabs" at new religions, self-improvement, and the Human Potential Movement. A form of Rolfing is also parodied in the film by Lotte Lenya, whose character Clara Pelf is seen as a spoof of "a Rolf-like masseuse". Big Ed Bookman is seen crawling around on all fours practicing something called "creep therapy" or "movagenics". Movagenics is seen in the film as a way for individuals to find their "lost center of consciousness". Big Ed Bookman is also shown proselytizing for "Movagenics", a fictional group in the film which "TIME" referred to in its review as both a cult and a new faith.
