A frequent thought of mine after watching a film is "this should have been an animation." I believe this was the first film I have seen where I thought "this should have been a audio program." The pleasures of this film are conveyed principally through voice and dialog; hearing Lynn Belvedere insult the suburban household he nannies.
I think it might have been interesting to release the entire thing as an audio program (this would require a narrator in parts), and then create a film afterwards that exactly superimposes on top of that.
