The DVD for "Hollywood Cavalcade" has three very short special features included on the disc. Together, the three probably would have worked a bit better because they just weren't very complete on their own. However, they are still worth seeing.
The film is a making of featurette for the movie. It mostly focuses on Alice Faye in the film and doesn't really talk much about her co-star, Don Ameche. The film discusses the parallels in the film to the real history of silent movies as well as the many divergent aspects of the movie. Overall, it's quite interesting and a nice accompaniment to the film but it also seemed a bit superficial and left me wanting more. Worth your time but too, too short.
