Blue Valentine has found itself mired in inadvertent controversy after it was given a NC-17 rating in the US, for one particular sex scene. Although not graphic, the scene is awkward to watch, and so the MPAA gave it the kiss-of-death rating, which the makers are now likely to try and fight. You certainly would expect controversy from this trailer, which doesn’t tell you much about the plot, but suggest some sort of love story. The films starts Ryan Gosling and Michelle Williams as a married couple, charting their relationship over the course of several years. For more info on why the movie got an NC-17 rating, head over to Deadline.
