I just noticed this when I watched the movie. Sorry if it is old news but in this movie there is a woman Called Isabella that performs in a bar/club that is reminiscent of outer heaven and the title of the movie is Blue Velvet. Coincidence I think not.
We all know that kojima is a big movie buff and maybe this is his way of paying tribute to the movie or he was just inspired by the movie.
On another note, When Kojima was making games he probably did not know that he would become so famous outside of Japan therefore he blatantly borrowed or "was inspired" by Western Movies.
