The film is highly stylized and shows some of the story of the dance as a sort of melodramatic docudrama. If this were all the film had to offer it might fall flat. Yet, somehow it works but the meat of the film are the interviews with various dancers. Most, mind you, are not professionals. One man cleans up a cemetary--not an official position, he does it for tips from the families of those interned there. And there are other interesting stories. It is a shame more time isn't dedicated to the lives of these dancers but there are, of course, time limitations. These old school dancers, named Milongueros, live the tango. The dance and how they feel about it, relate to it, is an intergral part of their very lives.
For Tango lovers an appearance by Juan Carlos Copes might seem more apropos than Duvall's. Director Jorge Zanada is an Argentine and this may show in the details and the accentuation of the sensuality and, indeed, the "machismo" associated with Tango.
Professional Tango Dancers, of a modern-type, make an appearance here as well--to be critiqued by some of the Milongueros. Again this is too brief and the viewer longs for more interaction. It is also, once again, hard to criticize because Zanada was making a film, not a miniseries. In fact, longing for MORE, from the film may be one of it's strengths. The novice, (me, for instance) will walk away wanting to see and know more.
The film was shot in the mid-1980s and is currently widely available on DVD.
