AHardcore is very accurate in its depictions of the porn industry in L.A. in the late 70s. For one, all of the porn stores and clubs George C. Scott is seen going into were real, as were all of the magazines and sex devices being sold inside of them. Sexually explicit film actor and model agent Bill Margold provided Schrader with many actual locations to film in and fact checked the script for accuracy. X Rated film actress Serena can been seen in a cameo role as the other woman in the motel sex scene with Season Hubley. That scene is very reminiscent of how lower budget hardcore movies were shot in the late 70s as many such films were shot in rented apartments or motel rooms. Also, the described hierarchy of pornography is also accurate to what actually existed, with cheap 8mm films being the cheapest and most common films in existance to higher budget 16mm and 35mm features which were frequently shot over the course of a couple weeks with larger casts and crews, as shown when Scott visits a higher bdget pruduction being shot on a highway by Vince Ramada.
