their intention in making the film. Eli Roth, for example, specifically states on the producer's commentary track for The Last Exorcism, that he and the other filmmakers will offer advice to people interested in making films, as well as film school students. He is a strong proponent of the educational use of audio commentary, having recorded five commentary tracks for his debut, Cabin Fever. He also recorded insightful commentary tracks, with Quentin Tarantino, for both Hostel films, in which the two horror movie fans share film-making anecdotes and offer advice on working in the movie business. Meanwhile, others (such as Steven Spielberg, Joe Johnston, Clint Eastwood, M. Night Shyamalan & David Lynch) feel commentary can de-mystify and cheapen a movie. Director Steven Spielberg has not recorded commentary tracks for any of his films. He feels that the experience of watching a film with anything other than his intended soundtrack detracts from what he has created. Woody Allen has a similar lack of enthusiasm for commentaries, stating, "I'm not interested in all that extra stuff. [...] I want my films to speak for themselves. And hopefully they do." Similarity, some of Joe Johnston's movies handled commentary by the special effects team (like Jurassic Park III and Jumanji), and by the author (October Sky). The only exception to this rule was Captain America: The First Avenger. Notable DVD audio commentaries A number of films and music videos released today feature audio commentaries. While many of them will not hold the interest of the casual viewer, specific releases stand out, mainly those with elements of historical interest or subject-specific information from expert advisors. For example, the inventor of the steadicam, featured throughout the audio commentary track for The Shining, discusses his work with the ground-breaking technology in several films leading up to that landmark production. Non-movie buffs may be interested in the anecdotes offered by advisors to the filmmakers, such as the FBI profiler commenting on The Silence of the Lambs (Criterion DVD release). Filmmakers and cast may reveal stories from behind the scenes, explain the process involved in their work, or simply offer additional laughs. Films The science-fiction movie Sunshine (directed by Danny Boyle) contains an audio track with physicist Brian Cox. The author and professor, who served as an advisor on the production, discusses scientific accuracies (and inaccuracies) depicted in the movie. The 2009 Blu-ray edition of the film Galaxy Quest
