1. The Ending: Friedking says it's meant to be ambiguious, that Burns will never be the same after his ordeal...he's still carying his leather outfit after finishing the case. As such it's a toss up who killed Ted, either Burns or his lover/roommate.
①关于结局：导演对结局的解释是这部电影旨在模糊不清，完成任务的Burns已经不是以前的自己，最后谁杀了Ted，Burns还是Ted室友？并没有给出明确答案。
2. Killer's identidy: Friedkin states he firmly believes there was more than one killer involved in the actual case, so he wanted to convey that feeling here also. The first killer (the "Martian") gets himself killed in the park by another killer (Friedkin says as much) and at the end whomever we see entering the Cockpit (Pacino, someone else?). The only link between them all is the voice we hear a few times (Friedkin refuses to explain it).
②关于凶手身份：导演坚信在真实案件中应该不止一位凶手，所以它通过这部电影传达了这个想法。第一个凶手在花园中被第二个凶手杀掉，且电影最后走入俱乐部的背影并不确定是谁。让人们觉得其实凶手是一个人的联系只是那个声音。
3. Stewart being the killer: He did kill at least the guy at the peep show, but likely not all victims were his. Friedkin says that police always would get whomever looked good enough as a suspect and try to pin all the murders on them and even cut deals if they go along with it. Remember the 8 year sentence offer.
③关于凶手Stewart：他至少杀了一个人，但并非全部。警方总将所有凶杀归咎于一位嫌犯身上，甚至只要嫌犯承认了所有谋杀，具体细节都不再追究。
4. The 40 minutes of cut film: Friedkin says it's mostly sex scenes at the clubs and that the plot wasn't affected by the cut.
④关于删减的40分钟：多为在俱乐部中的sex镜头，对情节无影响。
5. Questions unanswered: Friedkin states he meant to leave questions open and not answer them all.
⑤关于未回答的问题：导演旨在给大家一个开放性的结局，没有回答所有问题。
6. Pacino knowing Stewart's exact song: The "who's here, I'm here, You're here" even though the police got it inacurate from the drag queen. How does Pacino know it accurately? To link him to the killer (he's dressing the same, feeling the same turmoil, maybe even picking up after him in the end).
⑥关于Burns知道Stewart的歌"who's here, I'm here, You're here" ：警方从踩着高跟的drag queen处知道了这首传说中的死亡之曲，可是男主角是怎么知道的？这会不由让人把男主和凶手联系在一起。
