No... I have never heard of that movie... I'll check it out.
Anyway I would say that your definition about arousal and porn does not make much sense
It's like a local joke we have:
How does the Englishman, the Frenchman and our local man arouse their wife during sex? The Englishman - with refined manners and play, the Frenchman with fine wines, and stuff... and the local guy says in a most profane dialect: "I wipe off my dick in the curtains and the wife gets really, really aroused!"
