 The love scene between Tom Cruise (qv) and Kelly McGillis (qv)  was filmed after initial test screenings. Moviegoers complained that  there was no love scene, so the company obliged. McGillis, however,  had already dyed her hair darker for her next film. This is why the  scene is tinted blue. Also noticeable as a subsequent shoot due to  the longer length of Tom Cruises hair (particularly in front).
