From the New York Times, Anatomy of a Scene is a great example of self-directed, learner-controlled elearning. Viewers are provided a palette of scenes from a range of films. Each is voiced over with the movie directer discussing ideas and techniques behind scenes in the film. Viewers can adjust the audio levels between the scene and the director's commentary.
You will likely need a NYT account to view, but it is free.
For a film-buff like me, this is a candy store.
