At the beginning and end of the film, it is mentioned that it is "presented by" the Roerig division of Pfizer, a pharmaceutical company. Later in the film, the definition of the Greek word "ataraxia" is given. It is no coincidence that Pfizer sold a prescription drug with the brand name Atarax (hydroxyzine). So, this "public service" film is actually a long commercial for their sedative (among other uses) Atarax.
