This exquisite first film by Vincente Minnelli just came out on DVD along with another all-Black musical of the period starring Lena Horne, "Stormy Weather". As delightful as both those films are, and although they are produced by two different companies, their DVD presentation is marred by audio commentaries by the very same Dr. Todd Boyd, Professor of critical studies at USC. To call the man a pompous bore would be to imitate him by stating the obvious. These commentaries, which are all about painfully deconstructing every single aspect of the racial clichés and supposedly harmful depictions of Black people contained in those films and are full of precious profundities like "Notice how the dancers smile too much, which is a hateful racial stereotype", were evidently put together in a commendable spirit of political correctness. Unfortunately, the good Doctor has a tendency to repeat every worthwhile point he makes at least five times and is totally blind to the wonderful qualities of those films, with the end result that he robs the viewing experience of all joy, discovery, wonderment and spontaneity. He also fails to point out the qualities and positive aspects of each production and is totally unreliable when it comes to identifying wonderful performers (and performances) who will otherwise remain eternally nameless, undocumented and unpraised. The harm done is less pronounced on the "Cabin in the Sky" DVD, where his debunking and killjoy duties are somewhat mitigated by the presence of his colleague Prof. Drew Casper, who is at least knowledgeable about the films of Minnelli, and relatives of Eddie "Rochester" Anderson, who do a good job describing the human side of the real star of the film. "Cabin in the Sky" is one of the best fantasy-comedy-musical films ever made and boasts some of the best stage and recording talents of the XXth Century. When you watch it, do yourself a big favour: Enjoy it for what it is - a masterpiece - and turn Professor Boyd's platitudes off!!!
