Robert Johnson, Jr. and Diane Carson’s Other People’s Footage: Copyright & Fair Use is a documentary about exactly what its title says it’s about.  Per the film’s website, the doc features “illustrative examples from nonfiction, fiction, and experimental films that use pre-existing footage, music and sound from other individuals’ creations,” while drawing upon a solid roster of lawyers, archival producers and other specialists in this often-muddy field. In this clip, the late Haskell Wexler discusses his strategy in using a Coors commercial in his documentary Who Needs Sleep?, followed by some interesting insights on the strategies used by 20 Feet from Stardom and Bowling for Columbine. The full film is available for purchase on its website via Vimeo.
