I watched this on the Full Moon Features app, where Band kicks off the movie with a 10-minute explanation about how the film was "lost" (the first showing was so poorly received that he destroyed all of the prints) and until a negative print was "found" in the UCLA archives in 2010. This is the best part of the movie.
"Last Foxtrot in Burbank" is a satire of "Last Tango in Paris," with Machael Pataki mumbling his lines in the Brando roll, and Sherry Denton in the Maria Schneider roll. I have not yet seen (and am not really interested in seeing) "Last Tango" so I cannot comment on how closely "Last Foxtrot" follows the original, but there is not much to recommend about "Last Foxtrot," except for Charles Band completists.
Interesting -- Band numbers all of his films, but after destroying the original prints, he disavowed this one from his filmography, until it was found in 2010. He subsequently calls this Film 0.
