“Run, Run” is a charming 1965 short film by Jim Henson in which his daughters run through the woods behind the Henson house. Henson created the film to experiment with light, color, and music (the film features a song by Joe Raposo, who went on to compose for Sesame Street). For more on the film, see this post by Jim Henson’s Red Book.
