Fridge Horror: The movie ends on a rather upbeat and positive note, with the True Companions back together and ready to get back to work... however, the 1980s wasn't quite finished with bringing bad tidings to the porn industry. The spread of HIV/AIDS ravaged the industry, with many performers getting infected due to unsafe sex practices. Including John Holmes. Y'know, the inspiration for Dirk Diggler.
Not to mention what would happen to the porn industry once the INTERNET comes into play...
Fridge Brilliance: The movie ends with Dirk's exceptional penis being shown to the audience. Much like a "money shot" of a porno flick!
