What is this Once Upon A Time in Hollywood poster showing Margot Robbie as Sharon Tate? Standing in front of the Fox Village in her black turtleneck and go-go boots and blah blah. I’ll tell you what it is — it’s nothing. I’m also informing the Sony guys that the long, drawn-out Hollywood glamour-tease phase of this film’s marketing campaign is over here and now, and that things have to get more substantive from here on. Really. The first trailer (where is it?) has to have aroma, atmosphere and teeth.
