Niles, racism and the political subtext
It struck me watching this film again that a great deal of the plot (such as it is) concerns Niles and his bitterness towards America, presumably personified in his antipathy towards Vixen and her treatment of him. It comes to a head when a visiting Communist on his way to Cuba convinces Niles to join him, betraying Vixen and her husband on the way. He goes along with it until it becomes clear that the Communist villain is just as racist as the Americans Niles is turning his back on. The Commie's plan is defeated and Niles (and Vixen) are redeemed.
I was wondering if anyone had any ideas about what Meyer was driving at with this episode? It's essentially just a subplot but it does form the climax of the movie, and seems more or less entirely separate from the "sexual awakening"/liberation theme of the rest of the movie.
