The beloved holiday classic A Christmas Story is actually based on several stories from author Jean Shepherd, including his novel In God We Trust: All Others Pay Cash. It’s Shepherd who provides the voice of the narrator in the film version of A Christmas Story. (He also makes an onscreen cameo.) That’s just one of the Christmas Story facts in the latest installment of You Think You Know Movies!

The film’s fictional setting, Hohman, Indiana, is based on Shepherd’s real hometown, Hammond, Indiana, although the house that served as the home of the Parker family in the film was located on the west side of Cleveland, Ohio. Although the interior scenes were filmed on a soundstage, the house in Cleveland has since been renovated to resemble the one in the film, and now serves as a Christmas Story museum. That speaks to the enduring popularity of the movie; so does the fact that TBS and TNT have been broadcasting 24-hour Christmas marathons of A Christmas Story since 1997.
