"To me, a sex scene in a movie generally means a gratuitous scene that doesn't serve the story but gives a kind of excuse - we've got these two actors, we want to see them naked, so let's bring in the music and the soft light"

This quote by Joseph Gordon-Levitt speaks to the concept that sex scenes in motion pictures are often utilized as a way to turn on the audience, rather than to advance the story. He suggests that these scenes are often unneeded and are used as a reason to show 2 stars in a sexual scenario. He suggests that these scenes are frequently accompanied by soft music and lighting, which is suggested to develop a romantic atmosphere. This suggests that these scenes are typically used to create a false sense of intimacy between the characters, rather than to advance the plot. In conclusion, this quote suggests that sex scenes in films are often utilized as a method to draw in viewers, rather than to further the story.
