Stalking the Wild Cranberry (1974)

This wonderful film traces the steps taken in creating and shooting a television commercial for Post Grape Nuts. This film was produced by George Gage Productions, which filmed the commercial, starring the legendary Euell Gibbons, for the Benton & Bowles advertising agency, with lots of discussions & outtakes. The funky "Cranberry Rag" played by pianist Paul McDonough is delightful.
