Does anyone know some alternative means (no Net Flix, no online mass  
seller, etc)  of finding rare films for purchase? I'm looking for a  
1977 movie starring Athol Fugard that's known by three different  
names:  "The Guest at Steenkampskraal", "The Guest:  An Episode in  
the Life of Eugene Marais", and simply, "The Guest."  The obvious  
places to buy movies -- at least, obvious to me -- have turned up  
nothing. I'm something of a Marais completist, and I'd like to own  
the movie.

Thanks for the help,
